What is Salesforce?
Salesforce is a SaaS (software as a service), cloud-based Customer Relations Management tool.
Colin Johnson says
Salesforce was founded in 1999 by Marc Benioff and Parker Harris and has since become one of the leading CRM solutions in the world. It is. a versatile CRM platform that empowers businesses to enhance customer relationships, streamline operations, and drive growth through a combination of sales, service, marketing, and commerce solutions.
Regan DeShazo says
I would also like to add: The platform’s cloud-based architecture facilitates accessibility from anywhere, fostering a more agile and collaborative approach to customer engagement. As a pioneer in cloud computing for CRM, Salesforce has played a pivotal role in reshaping how businesses build and maintain meaningful relationships with their clients.
Hadeer Saad says
Hello Colin,
Salesforce has become, and continues to be an essential platform in the business world. Thank you for sharing when it was discovered and by whom.
Samir Lagouit says
Maurice,
I like how you described Salesforce as an SaaS. As we continued to use and learn about it in our maxlabs, I feel like we all saw how relevant it is to a business. Between how you are able to manipulate responses to various emails, and also generate sales leads. It is a software as a service, that has help revolutionized how CRM is viewed/used.

Crow’s foot notation is a widely used method for visually representing relationships in entity-relationship diagrams (ERD). Crows foot notation shows sections of a process and the relationships they have with each other. It also has the characteristics of each section. In exam 2 we saw this with the class registration process which i liked because it was an example that was easy for me to understand and that could be one of the reasons why it was my highest exam grade. I am also seeing this example online on the subject of waste management. It has the main section called “subject of waste management” and has it’s characteristics then has a line and days its located and has the location section. It has its characteristics as well. It keeps going with the other subjects and characteristics but I wont be going over them because this post would be too long.
Colin Johnson says
What are the different relationships in crow’s foot notation, and how do you express those relationships?
Crow’s foot notation is a widely used method for visually representing relationships in entity-relationship diagrams (ERD). In this notation, various types of relationships can be expressed, each conveying a unique connection between entities. One fundamental relationship is the “one-to-many,” where a single entity in one table relates to multiple entities in another. This is denoted by placing a crow’s foot symbol near the “many” side. Conversely, the “many-to-one” relationship is depicted with the crow’s foot on the “one” side, signifying multiple entities linking to a single entity. Additionally, the “many-to-many” relationship is illustrated by placing crow’s feet on both ends, indicating that entities on both sides can have multiple associations. Understanding and effectively expressing these relationships in Crow’s foot notation is crucial for designing robust databases that accurately model real-world scenarios, facilitating efficient data management and analysis.
Juan Delgado says
Hi Colin,
I liked how you explained the differences between each ERD form. Something that tripped me up during the lecture was the arrows for the crow’s foot notation. After reading this response, now the arrows make much more sense to me than before. I also just like how in-depth you went with your answer.
Georgios Zisis says
Hi Colin,
You did a nice job, with plenty of detail, of explaining the different kinds of relationships that the notation can have. There is another relationship “one to zero or many” illustrated with a circle just before the crows foot that indicates that the related entity is not mandatory. An example of this would be browsing on Amazon without making a transaction.
Ereny Abousaif says
Thank you for providing a detailed description of the differences between each type of ERD. I found the explanation of the arrows in the crow’s foot notation to be quite useful because I found it to be a little unclear during the presentation. My comprehension of this issue has much enhanced as a result of your response. Furthermore, your response’s breadth has been helpful in giving readers a thorough understanding of the subject. Your thorough explanations have helped me understand things more clearly overall. I appreciate you taking the time to respond with such clarity and understanding; it has helped to make the topic less intimidating and more approachable for me.
Zarmina Khan says
Colin,
The use of crows foot and the notation that is involved, is important when we think about designing a robust database. The description of the one to many symbol is also important and your description is very helpful.
Darren Nolan says
We have similar takes on crow’s foot notation but I give an example while you get in-depth. I bet if someone read both our of posts they would be able to understand it pretty easily. Your first then mine of course.
Hawa Barry says
Hi Colin,
Your attention to detail with crow’s foot notation really drives the nail on the head. Your post was helpful in further elaborating on it.
Danylo Pidkova says
What are Dynamic Dashboards and what are their functions?
Dynamic dashboards are powerful data visualization and analytics tools. These dashboards are interactive and capable of adapting to real-time changes, providing users with dynamic insights. They connect to live data sources, enabling users to view the latest information instantly.
Dynamic dashboards offer real-time insights through interactive interfaces. These dashboards utilize charts and graphs to consolidate information from various databases or applications, providing a holistic view of organizational performance. By integrating data visualization techniques and concepts they enable users to ask questions, explore trends, and make informed decisions. One key function is the ability to customize the dashboard based on user preferences and requirements. Users can interact with the data, adjusting parameters and filters to tailor the dashboard to their specific needs.
Dynamic dashboards play a crucial role in problem-solving across industries. For example, in marketing analytics, they can unveil customer behavior trends for targeted strategies. Utilizing dynamic dashboards in a business enhances decision-making processes and overall organizational efficiency.
Ajibola Sode says
Hey Danylo,
You are right. Dynamic dashboards are real-time, interactive, customizable tools that integrate and display data from multiple sources. They enhance data visualization, facilitate informed decision-making, and improve organizational efficiency. Their versatility finds applications across various sectors, making them key tools in the modern data-centric business environment.
Jenna Oldroyd says
Hi Danylo,
You did a great job explaining what dynamic dashboards are. Dynamic dashboards are great tools for companies to use to monitor their sales. As you said, it can be customized according to the viewer’s needs. It gives the viewer a real-time, up-to-date view of their platform.
Ereny Abousaif says
I appreciate your thorough description of the distinctions between the several kinds of ERD. I found the crow’s foot notation to be a little puzzling during the lecture, so the explanation—especially with the arrows—proved to be quite helpful. My comprehension of this topic has much improved as a result of your response. Another benefit of your explanation’s richness is that it gives readers a complete understanding of the subject. Overall, I feel that I can now understand the material better because to your thorough explanations. I’m grateful that you took the time to answer with such lucidity and comprehension, demystifying and humanizing the matter.
Hadeer Saad says
Hey Danylo,
I enjoyed reading your post! Dashboards are significant data tool because they can adopt to anything quickly. Dashboards are essential for businesses, hospitals, and schools.
Max Smith says
What is Salesforce?
Salesforce is a company which specializes in customer relationship management. Furthermore, Salesforce gives businesses a centralized location to store, track, and manage customer data.
Eduard Lagutin says
I like your evaluation and description of what sales force is. I feel that salesforce, while complicated, can be a great tool for any business to keep track of data and automate a lot of tedious tasks.
Zarmina Khan says
ERD tables – key things?
An ERD is a visual representation of the entities, and attributes within a database. When designing a database creating an ERD is an essential step. Entities, identify and define all the entities relevant to the system or business. Attributes, are the properties of the entities, ensuring that they capture all relevant information. Primary Key is a unique identifier for each record in a table. Common choices include a single attribute, or combination of attributes. Foreign key, relationships, cardinality, normalization, data types, unique constraints, and indexing are all key considerations that need to be addressed when we create a well structure and efficient ERD that accurately represents the relationship and structure of your database tables.
Juan Delgado says
Hi Zarmina,
I liked how you explained the key things for ERMs. How you explained what goes into an ERM what the symbols are and what they represent. I also really enjoyed how you explained what goes into the entity. Like how IDs are the primary entity. Overall, I enjoyed this response.
Juan Delgado says
What are the primary symbols?
An entity is like a noun. This is usually represented by a rectangle. An entity is like the actors from the swim lane diagrams. That is not always the case, but it happens sometimes. An attribute is like an adjective. This is usually represented by an oval. Attributes describe what an entity is all about. Attributes describe what is the data for the entity. There is always a primary attribute which is usually an ID. It doesn’t matter what entity it is, the primary attribute will be someone’s ID. Then, the attributes will describe what a worker does. What data would we need to know about that worker? We would need to know they’re name, phone number, and email. It would be different for other types of situations though. A relationship is like a verb. This is usually represented by a diamond. A relationship connects each entity with an arrow. The relationship describes that arrow and why this connects with each other. The arrows can go in any direction within the entities.
Elena Grigoryan says
I like the comparison to noun, adjective, and verb. It helps remember what these keys represent!
Cheyanne Kostaras-Nesbitt says
Hi Juan!
I like how you mentioned the parallels between the entity relationship diagrams and the swim lane diagrams. This is a great connection considering they typically go hand in hand. Great detail in your response. If anyone is confused on the symbols, this comment would provide great clarity.
Colin Johnson says
Juan,
I agree with others that the relation of the symbols (rectangle, oval, diamond) to nouns, adjectives, and verbs is very useful when we are attempting to create our diagrams. Having never created these diagrams in the past, I know this will be an easy reference point to use in future situations both in this class as well as in professional settings.
Corey Reagan says
Juan,
I like how you broke this down for me and made it much more easy to follow along and picture it in my head. Well done!
Zarmina Khan says
Juan, the primary symbols involved are important when we have to deal with databases and swim lanes. You clearly have a good understanding of how the relationships work with one another, as well as the description involved.
Ajibola Sode says
An ERD is a visual representation used in database design to illustrate the relationships between different entities in a database. Critical components of an ERD include entities, attributes, relationships, and cardinality and modality. ERDs are crucial in organizing and structuring data in a way that ensures the database system is efficient, scalable, and meets the requirements of the applications that will use it.
Eduard Lagutin says
Hi Ajibola,
I feel that your description and definition of what and ERD is is great. I like that you included the critical components of ERDs and how they can be critical in organization and structuring.
Ajibola Sode says
Additionally, ERDs prove to be essential in enhancing communication between all project stakeholders, such as database designers, developers, and business analysts. They provide a unified language and structure for discussions about the database design and its alignment with business needs and goals. With the advancement of technology and the increasing complexity of databases, employing ERDs for the visualization and planning of database architectures remains a critical strategy. This approach ensures that database systems are effective and successful in facilitating business operations and decision-making processes.
Cristina Valentin says
What is an ERD?
An Entity Relationship Diagram is a diagram type used to show data and how that data is related. The diagram with have Entities which are the nouns of the diagram. The Entities can be several different nouns such as people, documents or systems. The ERD will also include Attributes which describe the Entities, the most important Attribute about an Entity is called the Primary Key. Lastly, the diagram will also include Relationships which are the verbs or actions taking place. These relationships link the Entities through activities that connect them. However, not all Entities have to be linked together through the Relationships.
Regan DeShazo says
Yes correct, also by visually mapping out the relationships between different elements, ERDs contribute to the clarity and efficiency of database development, ensuring that the resulting database accurately reflects the business requirements and relationships between data entities.
Jenna Oldroyd says
What is Salesforce?
Salesforce is a cloud-based CRM (customer relationship management) software.

Salesforce is used by many Fortune 100 companies to enable and enhance business.
Briana Seidle says
Thank you for this clear and simple explanation of Salesforce. Going directly to the website to observe the software could be very overwhelming without first reading a description of it.
Elena Grigoryan says
Cardinality is pretty much an element relationship between entities. It shows the number of elements in one entity that is associated with the number of elements in another entity. The common three types of cardinality are one-to-one, one-to-many, and many-to-many.
One-to-one cardinal relationship shows that only one element in the one entity can be linked with only one element in the other entity. Many times, it is used to split an entity into two to make data easier to understand. For example, Employee-Employee Profile.
One-to-many cardinal relationship shows that one element in the first entity could be linked to many elements of the second entity, but one element of the second entity can only be linked to one element of the first entity. Our professor came up with a great example, which is course instructor could be linked to many students, however, students can only be linked to one course instructor.
Many-to-many cardinal relationship shows that more than one element of one entity can be linked to more than one element of the second entity. For example, visitors can be linked to many cities (people visiting cities), and cities can be linked to many visitors (cities traveled by visitors).
Rachel Bard says
The first time I was reading about cardinalities it felt like I was learning a new language. Once the cardinal symbols for many, one to many, zero or one, etc. I had to take an extra few minutes to really read through and make sure I understood the the crows feet symbol stood for many. I still see myself making flashcard in the near future to make sure I really understand!
Eduard Lagutin says
ERD (Entity-relationship model) is a type of model or flowchart that shows us how different entities relate to each other within a system. Unlike a typical flowchart ERDs more look at where data is stored, transferred, and used. ERDs are typically used in database design, troubleshooting, education, and research. The two notations of ERDs are the Chen’s Database Notation, which bares more similarities to a traditional flowchart, and Crow’s Foot Database Notation, which is a more modern and condensed way of making an ERD.
In Crow’s Notation there are three main ways to describe a relationship.
A 1:1 (one to one) which looks like this: -|————–|-, where a line connecting between two entities has a vertical line at both ends.
A 1:m (one to many) which looks like this: -|————————–<-, where a crow foot is found on both sides of the connecting line.
Eduard Lagutin says
CORRECTION:
At the very bottom something happened where it did not fully put in what I wrote.
“A 1:m (one to many) which looks like this: -|————————–<-, where a crow foot is found on both sides of the connecting line."
Should be,
"A 1:m (one to many) which looks like this: -|————————–————<-, where a crow foot is found on both sides of the connecting line."
Eduard Lagutin says
It should say that there is a crow foot on one end and a vertical line on the other and I had a final one that was a m:m but it keeps deleting it.
M'Kyah Graham says
Hi Eduard, helpful.
The visual representation was unique and rather helpful. While explaining the notation of an ERD is very helpful, being able to actually see the crow foot added extra understanding. Great inclusion!
Cheyanne Kostaras-Nesbitt says
What is an ERD?
An ERD is an entity relationship diagram. These can be used to visually display relationships between entities in a database. They can assist in designing new databases, understanding existing databases better, and restructuring databases for better performance. They show relationships between people, things, ideas, and events. Entities are the nouns (people or things), and the attributes are listed below, typically in a square or rectangle shape. The relationships are then shown by symbols connecting the different entities. They can be connected using symbols showing different types of relationships, such as one to one, one to many, many to many, many to one, etc. They can also include “none” in the relationships.
Max Smith says
I agreed with your description of an entity relationship diagram. I appreciated your in-depth explanation of how the diagram better models different databases. Finally I liked how you laid out the visual components that make up an ERD diagram.

They can assist in designing new databases, understanding existing databases better, and restructuring databases for better performance. They show relationships between people, things, ideas, and events. Entities are the nouns (people or things), and the attributes, or characteristics of the entity that are relevant to their relationships, are listed below, typically in a square or rectangle shape. The relationships are then shown by symbols connecting the different entities. They can be connected using symbols showing different types of relationships, such as one to one, one to many, many to many, many to one, etc. They can also include “none” in the relationships. These diagrams are helpful for new databases, understanding existing databases, or revamping databases because it clearly outlines the different “moving parts” and how they all relate to one another.
Georgios Zisis says
What are the primary symbols?
An entity is thought of as a noun, a definable thing or concept within a system. Entities are represented by a rounded rectangle with the name on top and its attributes listed below in the rest of the rectangle. It is important to note that when comparing an ERD to a swim lane the actors from the swim lane are going to be the entities, but there are usually more entities than actors. An attribute is a property or characteristic of an entity. Attributes are represented by ovals and have a key attribute that is a unique distinguishing characteristic of the entity. A good example of a key attribute is a persons ID. Everyone has an ID but no two are the same. Then the rest attributes are the characteristics such an email or phone number. Relationships are represented by diamond shapes and show how two entities share information. An arrow labeled with a verb connects the relationship between two entities. For example, a student and a course are two entities. An arrow labeled with “enroll” will connect the two entities.
Rachel Bard says
An ERD is an Entity Relationship Diagram. An ERD is a visual representation of how information is related. The entity is the noun. The relationship is the verb, shows how entities interact with one another. An ERD is filled with attributes, also known as properties or traits of the entity.
Hamida Akther says
Hi Rachel,
I like your answer. ERD is a conceptual and representational model of data used to represent the entity framework infrastructure through the visual graphical representation.
Dana Persaud says
Great explanation!
ERD’s are extremely as visual representations, and an important key is the information within the ERD! They are similar to the diagrams we practiced before but definitely different when it comes to the information within the ERD.
Briana Seidle says
What are the primary symbols? Entity, Attribute, Relationship
Entity – Represented by a rectangle, is an object or concept that is used to store information. A weak entity is an entity that is defined by a foreign key relationship with another entity; it cannot be uniquely identified on its own.
Attribute – Represented by an oval; a key attribute is a unique and distinguished characteristic of the entity. A multivalued attribute has more than one value. A derived attribute is contingent on another attribute.
Relationship – Represented by a diamond, shows how two entities share information or how they’re linked. They can also be self-linked.
Each of these symbols are connected by solid lines which connect attributes and show the relationships between the entities in the diagram.
Leanne Sheely says
Great explanation for these. I curious what this will look like once we do more of it in class especially the relationship one. This will be a good post to reference if I ever have questions about this.
Corey Reagan says

What is an ERD?
An Entity-Relationship Diagram (ERD) is a visual representation of the structure and relationships within a database. It is a powerful tool used in database design to model and illustrate the logical connections between various entities, attributes, and their associations. ERDs are comprised of entities, which represent real-world objects or concepts, and relationships, which depict the connections between these entities. Attributes, the characteristics or properties of entities, further define the structure. ERDs follow a standardized notation, often utilizing symbols such as rectangles for entities, diamonds for relationships, and ovals for attributes. These diagrams serve as a blueprint for database developers and stakeholders, aiding in the conceptualization, design, and communication of database structures. By visually mapping out the relationships between different elements, ERDs contribute to the clarity and efficiency of database development, ensuring that the resulting database accurately reflects the business requirements and relationships between data entities.
Salvatore Marsico says
Hi Regan,
This post was very enjoyable to read about what an ERD is. An ERD is a powerful tool used in many different fields of business and is very beneficial to those who do use it. They clarify and provide efficiency for database develop and especially information systems.
M'Kyah Graham says
Hello Regan,
You really dove deep in your explanations of ERDs. I actually learned a bit more about the notation of ERDs. For example, that diamonds, rectangles, and ovals were used to relay different characteristics throughout the diagram. Very helpful explanation !
Leanne Sheely says
What are the different relationships in crow’s foot notation, and how do you express those relationships?
When it comes to the crow’s feet notation it looks a little weird and looks like it’d make no sense if you don’t know what it means. Once I explain it I hope you’ll understand it so much better. I wish I could upload a picture to show you but it won’t let me so jus try to imagine it or you can google crow’s feet notation. There are many different variations of crow’s feet notation. The first one is one to one which kind of looks like -|—|- . This means that there is one provider and one receiver. The next one is one to many which looks like -|——<- . This means there could be one or more provider and one or more reciever. Do you kind of get the idea now? The next ones are the same exact concept but if you put a circle in front of the reciever in front of any of the symbols it means it could be zero or one or many depending which symbol is on the reciever end. One thing to always remember too is there can never be a circle on the provider side meaning there can never not be a provider. I hope this helps and makes a little more sense.
Salvatore Marsico says
Hi Leanne,
I enjoyed reading your post about the two different ERD notations. They are definitely weird to look at and understand. Your explanation made it very clear of the different notations and how they are both used.
Salvatore Marsico says
What is an ERD?
An Entity Relationship Diagram (ERD) is a flowchart that gives a visual illustration of how entities, which can be people, objects, or concepts, relate to each other in a system. We see ERDs mostly in the fields of software engineering, business information systems, education, and research because ERDs are used to design or debug information systems. To make the ERD more simplistic, it uses symbols to differentiate entities, relationships, and actions within the system.
What are the two notations of ERD’s
The two notations of ERD’s are the Chen notation style and the Crow’s Foot Database notation. The Chen style compares ERD to a grammar diagram involving common nouns, proper nouns, verbs, adjectives, and adverbs. The Crow’s Foot style shows many different adjectives associated with an entity.
What are the primary symbols?
The primary symbols of an ERD are rectangles, circles, and diamonds. The rectangles represent entities or nouns, circles represent an attribute or adjective, and diamonds represent relationships or verbs.
Hawa Barry says
Hi Salvatore, this is a nice, in-depth explanation of the ins and outs of ERD.
Hamida Akther says
What is an ERD?
An Entity Relationship Diagram (ERD) is a visual graphical representation of an organization’s different data storage requirements. By using conventions that describe how these data are related to each other. It is a flowchart that illustrates an information system’s entities and the relationships between those entities. Entities such as people, objects or concepts related to each other within a system. ERD illustrated the logical structure of databases, which is most used in the fields of software engineering, business information systems, education and research. ERD uses a defined set of modeling objects symbols like rectangle, diamond, ovals and connecting lines to represent the entity framework infrastructure. ERD is a conceptual and representational model of data that simplifies the problem to be solved while retaining its essential features. The components and features of an ERD include three database notation: entity, attribute, and relationships. Entity (noun) defines things like person, objects or event. EX: student, shopper, item. Attribute (adjective/characteristic) a property of an entity ex: item price. Lastly, relationship (verb) is how entities act upon each other or are associated with each other ex: buys.
Lesly Puma Vinansaca says
Hi Hamida
Great explanation of what an ERD is, it was also very insightful. An ERD is a powerful tool for the fields you mentioned, like software engineering, business informative systems, and research.
Madison Masino says
Salesforce is software used to provide relationship between customers and management. This is a tool that makes things easier to close deals, connect with people and find future prospects. Also, as we do our maxlabs on salesforce, we are learning how to navigate the system. Although the labs we do are fake, it has already shown many reasons in which this should be used by every business owner. It’s almost a one stop shop for business owners to keep track of everything.
Mahbuba Ahmed says
Hey Madison,
Salesforce is a great tools for business. It simplifies the entire process and offers an overall solution for managing customer relationships and the Max labs are a great way to practices the functionalities of salesforce.
Samir Lagouit says
What is an ERD?
An ERD is an Entity Relationship Diagram. It gives a visual representation of various types of data, using different descriptions to define the data. An Entity is for Noun’s, normally the major thing you are talking about within your data. While an attribute is used to describe that major person/thing you’re talking about in your data. Then a relationship can describe how that data point relates with another one, you have described or available in your visual representation.
Samir Lagouit says
What is Salesforce?
Salesforce is a growing Consumer Relationship Management platform that is designed to for B2B purposes. It’s a software that has many uses in the business world and is currently in demand at many companies. It allows you to analyze your companies’ data, streamline communication with customers, and do so and in a simple structure. One of the major selling points on salesforce is how easy it is to use, and the way it easily scales with the amount of information being used.
Lancelot Nyandoro says
I couldn’t have said it better myself, Samir. But I also add that salesforce works or focuses on areas that look more at the customer service side of things. Such as how the marketing tools reach and influence the customer. Unlike ERP or SAP systems that focus on how the business turns inputs into output at what rate of time and cost, salesforce looks at how the company can being and return more customers.
Dana Persaud says
What is ERD?
ERD is a visual representation of how data relates to each other. Much like system planning and swim lanes ERD’s work as a visual aid to understand how other information works with each other, The key difference that can be noted between ERD and swim lanes are the symbols, In ERD’s they use ovals, rectangles and diamonds as entities, attributes and relations. ERD’s also have verbs connecting each other as well as specifically lines or crow’s feet for each element within the ERD. Finally, ERD’s hold more managerial information about an entity rather than an action telling a story. They will often hold a location, ID, or registration number needed in relation to the other information.
An easy example of an ERD is linked below~ https://i.ytimg.com/vi/BaN7Ng7a82Y/maxresdefault.jpg
Maurice Chism says
Dana,
I believe that ERDs are easier to follow and understand. I am having difficulty with the functions of swim lanes and who should be in what actor etc. I believe that ERDs can provide a simplier way of understanding where the process begins and ends and who has what function.
Ereny Abousaif says

Great breakdown.
M'Kyah Graham says
This week, our assignments consisted of the use of Salesforce. After becoming more familiar with its content and purpose, I understand Salesforce as a versatile business tool. It allows businesses to create an app used for practically any particular task they might see fit. It is ideal for the collection and management of data. And the layout of the platform is completely at its owners discretion— how it looks, functions, the data it collects and reveals… Everything. We were tasked with creating an app that manages sale pitches, and other important information associated with each meeting. In gaining familiarity with the app, I understood that Salesforce can also create charts and diagrams relative to the data inputs, create and hold contact (and contact information), make predictions and analyzations based on data inputs and so much more. Though it is a bit difficult to navigate initially, the more it is used the better. It is a rather useful in developing users’ technological skill and understanding, while also efficiently keeping track of an organization’s content.

M’Kyah, I agree that the software can be a bit confusing. But once I continued to use it certain process became easier. There were moments that I could not remember where certain functions were. So I as a business person would use this a process. I have used other software similar to it named vCita. I believe this software was more user friendly. I think with Salesforce, you would need to have an idea of programming to understand where to look for certain functions.

ERD is an entity relationship diagram that illustrates entities in the system, such as people, objects, or concepts, that relate to each other, and most often, people use it to design or debug relational databases on the fields of software.
Lancelot Nyandoro says
Yes, Hader! ERD gives titles to jobs performed by people and systems. For example, instead of a step or process going thru a person, we tend to look at positions such as an accountant as a station. So instead of saying, “we going to get Anna to look at the number” we would just push the job to the accounting department
Erica Griggs says
Hello Hadeer!
I chose ERD as well I think your breakdown highlighted important concepts of ERD!
Mairaliz Negron says
Hi Hadeer,
I also chose this question. I think you defined what an ERD is to a T. I like how your definition is easy to understand. Even if someone knows nothing about what an ERD is, this would be a great definition for them because it’s easy to grasp. Overall, great explanation and breakdown!
Dylan Milano says
When exploring ERDs, one encounters two prominent notations – the “Crow’s Foot notation” and the “Chen notation”. While the Chen notation emphasizes mapping relationships between entities, the Crow’s Foot notation depicts cardinality and participation of entities in a relationship. How do these notations differ in representing complex data relationships and entity attributes?
Within ERD representations, fundamental symbols such as “Entity, Attribute, and Relationship” play pivotal roles in defining the structure and connections within the database schema. How do these symbols come together to create a coherent visual depiction of data entities and their interconnections?
Transitioning to the dynamic realm of “Salesforce”, it’s crucial to understand its significance as a leading cloud-based CRM platform. Salesforce enables businesses to manage customer relationships, streamline processes, and drive growth through data-driven insights and automation. How can leveraging Salesforce revolutionize customer engagement and organizational efficiency?
Erica Griggs says
Good breakdown Dylan. I chose the same topic as well!

“Demystifying ERDs: The Blueprint of Data Organization”
In this week’s MIS discussion, let’s unravel the acronym mystery and delve into the world of Entity Relationship Diagrams (ERDs). An ERD is like the architect’s blueprint for databases, a visual representation of how data entities relate to each other. It breaks down complex data structures into a clear and concise format, making it a crucial tool in the world of information systems.
Imagine it as the storyteller of databases, where entities are characters, and relationships are plotlines. ERDs simplify the process of designing and understanding database systems, fostering efficient communication between developers and stakeholders.
Whether you’re an aspiring data architect or just starting to dip your toes into MIS, understanding ERDs is the key to building robust, well-organized databases. Join the conversation, share your thoughts, and let’s demystify the language of ERDs together!
Lesly Puma Vinansaca says
The two main notions for ERDs are Crow’s Foot notions and Chen’s notion. Crow’s Foot notation is a popular graphical representation for ERDs. In this notation, entities are represented as rectangles, attributes are depicted within ovals, and relationships between entities are shown using lines connecting them. Chen notation is another widely used notation for ERDs. In Chen notation, entities are represented as rectangles, attributes are listed within the rectangles, and relationships between entities are depicted using diamond-shaped symbols.

What is an ERD?
ERD stands for “Entity Relationship Diagram”. A ERD is a visual representation of different data using conventions that describe how these data are related to one another. An ERD is a powerful and useful. It’s a helpful tool that allows us to see the visual structure of a database and to better understand connections and relationships within a database.
Leanna Paul says
Hi Mairaliz, absolutely, an ERD is a vital tool in database design and management. This visual clarity is crucial for effective communication and collaboration among stakeholders. Good post!
Jorgelina Rodriguez says
hey mairaliz, agree with you 100% on this statement
Leanna Paul says
Salesforce is a cloud based CRM software which allows companies to easily find more prospects, close more deals, and connect with customers in a way that they can provide them with amazing service. Salesforce brings together tons of data from any source with the use of artificial intelligence. This database helps employees at companies that use SF work more productively and better deliver the personalized experiences customers love.
Jorgelina Rodriguez says
In database administration, one-to-one, one-to-many, and many-to-many relationships are examples of cardinality types. Every record in one entity matches perfectly to one record in another when there is one-to-one cardinality. Each record in one entity can be connected to several records in another entity if there is one-to-many cardinality. numerous records in one entity can be linked to numerous records in another entity, a feature known as many-to-many cardinality. Designing effective database structures, maintaining data integrity, and maximizing query efficiency all depend on an understanding of cardinality. Database developers can create meaningful links between things and realistically simulate real-world circumstances inside the database system by setting cardinality.

What is an ERD?
An Entity-Relationship Diagram (ERD) is a visual representation that illustrates the relationships between entities within a database system. It serves as a blueprint for designing and understanding the structure of a database by showcasing how different entities relate to each other. Entities represent the various objects or concepts within the system, such as customers, products, or orders. Relationships depict the associations or connections between these entities, highlighting dependencies or interactions.
ERDs typically consist of entities represented as rectangles, attributes depicted as ovals or circles within the entities, and relationships portrayed as lines connecting the entities. ERDs help database designers and stakeholders conceptualize the database schema, identify key entities and their attributes, and define the nature of relationships between them. They play a crucial role in database design, development, and maintenance, facilitating effective communication and ensuring the integrity and coherence of the database structure.
Kerri McGuckin says
Hi Hadeer,
Your post gave a lot of information on how ERDs work. When we learned about ERDs in class, I didn’t immediately relate them to being used to create databases. I was comparing them a lot to swim lanes, which I think are more helpful for operational workflows. I work in operations, so the swim lanes have been much easier for me to understand overall, have you had a preference of either model?

ERD stands for “Entity Relationship Diagram.” An ERD is a type of flow chart that illustrates how different entities relate to each other within a system. Entities can be a range of things such as people, places, concepts, objects… etc. These types of diagrams are normally used to design databases and can be used in many different fields of work, but are often used in software engineering.
The two notations for ERDs are Chen’s Database Notation and Crow’s Foot Notation, both use different types of symbols. In Chen’s Notation, each symbol means something different. A rectangle is used to symbolize a noun or an entity. An oval is used to symbolize an attribute or an adjective. and a diamond is used to symbolize a relationship or a verb.
In Crow’s Foot Notation, the attributes of the entities are outlined in a rectangle and they are connected with lines that symbolize a relationship or verb between the two entities. On these relationship lines, there are different symbols added to them that signifies whether a relationship is strictly 1:1, 1:many, many:many, 1:none… and so on.
Hawa Barry says
An ERD is an entity relationship diagram; essentially, it’s a visual representation of different data using conventions that describe how all this data is related to each other. Following Peter Chen’s notation, an entity is a noun, an attribute is an adjective, and the relationship each entity has is a verb. ERDs are especially helpful in simplifying the connection between different sets of data. Crow foot’s notation also explains the relationship between one or multiple entities but includes a little circle that indicates a null value as well. For those, related entities aren’t necessary. I found ERDs to be a good way to fully understand different components of an entity and therefore connect them all together.
Daniel Taylor says
Hello Hawa thank you for your post and helping me understand what ERD is. Knowing this skill will help me in the future for this class and hopefully my future career.
Dana Persaud says
What is ERD?
ERD stand for Entity Relationship Diagrams. Entity Relationship Diagram is a visual representation of how data relates to each other. Much like system planning and swim lanes ERD’s work as a visual aid to understand how other information works with each other. For some people ERD’s are preferred. The key difference that can be noted between Entity Relationship Diagram and swim lanes are the symbols. In Entity Relationship Diagram’s they use ovals, rectangles and diamonds as entities, attributes and relations. ERD’s also have verbs connecting each other. ERD’s also have specifically lines or crow’s feet for each element within the ERD. Finally, ERD’s hold more managerial information about an entity rather than an action telling a story. They will often hold a location, ID, or registration number needed in relation to the other information.
