-An ERD is a way to display how the data in a process relates to one another, and provides a way for the viewer to differentiate between different types of data, such as entities, attributes, and relationships.
-ERD’s are notated through either Chen’s Database Notation, or through Crow’s Foot Database Notation.
-For an entity, the primary symbol is a blue rectangle. For attributes, the primary symbol is a yellow oval. For relationships, the primary symbol is a gray diamond.
-In crow’s foot notation, the relationships can be described as one to one, one to many, and many to many. A one to one relationship is expressed as closed on both ends- there is only one option for either end of the transaction. A one to many relationship is expressed with one of the ends of the relationship being open-ended, and one being closed. A many to many relationship is expressed with both ends being open-ended for multiple values possibilities.
-ERD tables utilize the verb on the arrow that goes between boxes. The entity is shown at the top of the table, and the attributes to this are listed within the boxes.
-Salesforce is a program that allows businesses/individuals to create their own systems for users/customers to utilize their product.
-In Salesforce, a user can create a specific program/dashboard that allows others to access the same program. The user can enter information and search by this information, and can add filters and change the available information to create a comprehensive analysis of said information.
-The three types of cardinality are one to one, one to many, and many to many.
-Your digital identity is who you are on the internet and what you present to the online community. The identity is mismanaged through promotion, authentication, privacy, security, reputation, and networks.
-It is important to have a good digital identity in order to build your professional reputation, and to connect with others in relevant settings.
-The community platform integrates web, professional development, and coursework. It allows for social exchanges, collaboration, and digital branding through websites, e-portfolios, professional programs, and courses.
-The purpose of building an e-portfolio is to be able to share your works with others in your field to create a professional network among peers.
Hi Oceana,
I agree with your response to what Digital Identity is. Like you mentioned, it is basically who you are on the Internet. It is also gathered information about you that is being displayed online. It is important to be careful with what you want shown on the Internet because any information that is posted, it will stay there permanently and there really is no way to delete that information.
Hi Oceana,
Great post. The digital identity is one that I feel is underestimated by. some. This is many times the only impression that employers have of you, I like your recommendation to have a good digital identity in order to build a professional reputation.
Hi Oceana, I definitely agree with you on why its important to have a digital identity, I wrote similar points as your digital identity can be accessed by everyone, and especially employers so building your professional reputation online is the key now and especially in the future. Also e-portfolio helps you network and if somebody searches something in the create that you have, it will build relationships.
Hey Oceana,
I really like your purpose for building a e-portfolio. Not only is an e-portfolio important to let potential employers know who you are, but I also great at creating a professional network among peers. Great stuff!
– An ERD, known as an Entity Relationship Diagram, is defined in the powerpoint as “a visual representation of different data using conventions that describe how these data are related to each other.”
– The two notations for ERD’s are Chen and Crow’s foot.
– The primary ERD symbols are an entity, attribute, and relationship, those being a rectangle, an oval, and a diamond, respectively.
– The different relationships in Crow’s Foot notation are a one-to-one relationship, a one-to-many relationship, and a many-to-many relationship. A one-to-one relationship is expressed as a horizontal line with a small, vertical line crossing over on each side of the line. A one-to-many relationship is expressed as a horizontal line with a vertical line crossing on one side, and three lines shooting out on the other side to symbolize the “many” in “one-to-many.” A many-to-many relationship is expressed as a line with three lines shooting out on each side. Each relationship notation may include a small circle, which indicates a null value.
– A key thing about ERD tables are that each component must reach the next component before moving on, as well as that the notation that connects each component is drawn out to symbolize the relationships between them.
– Salesforce is a cloud-based software company that helps businesses in customer relationship management.
– Dynamic Dashboards are dashboards that allow for use between multiple users, as opposed to a singular user. Dashboards are Salesforce graphics that are designed to show data from reports within Salesforce.
– The three types of cardinality are the one-to-one, one-to-many, and many-to-many relationships.
– A person’s digital identity is the online collection of information about that person. To manage that identity, a person can add layers of protection to their online presence, such as anti-virus software and proper passwords.
– It is important to have a good digital identity to be able to establish a connection with others online, whether it be personal or business related.
– The MIS community platform is a website built upon WordPress, and is the central hub for MIS classes at Temple.
– The purpose of building an e-portfolio is to create a collection of online work, as well as to create a connection between others online.
Hi David,
I agree with your response to the last question on what an e-portfolio is. To add on to what you said, e-portfolios are a great way to send information about you to a specific job you are applying for so companies or businesses know what you have accomplished and what are you capable of doing. This can also apply to college applications.
Hi David,
Salesforce has many benefits and is revolutionizing the systems industry. I particularly like the dynamic reporting. This is a great way to display data gathered in the tool to multiple users.
Hey David:
Regarding managing the digital identity, you should also a VPN and have an encrypted connection which is a secure and safe way to safeguard it from hackers and identity thefts. Always remember to periodically change the passwords to difficult ones.
Hello David,
I agree with your response to the questions. You answered each one clearly and straightforward with was easy to follow and understand.

What is the MIS community platform? 4.1 (Slide 16)
It’s a cloud based platform built on wordpress. Integrates web, professional development, and coursework.
What is the purpose of building an e-portfolio? 4.1
To demonstrate your experience and work for employment opportunities and professional connections.
Hi Anthony,
I agree with you on why it’s important to have a good digital identity . I also mentioned that employers often will look you up online so its important to always stay professional. I like how you wrote that building an e-portfolio demonstrates your experience, e-portfolio makes it easier to share your information when networking.
Hey Anthony:
Not only does having good digital identity good for employment but it helps to identify who you are for verification purposes since identities can be stolen online by hackers or scammers. I’ve had to do personal verifications for loans and other personal matters and it blows my mind how they know where I lived 15 years ago, what my mother’s maiden name is. It lists the question, “which address have you lived in” and it lists a few and you have to select which is the correct one. They have this information stored about me. Nothing is private anymore.
Hey Anthony,
I really like your description of the MIS community platform. It is really a very organized tool with a lot of facets for our success. Well done!
Hello Anthony,
Your response to week 2 questions were straightforward which was great and easy to follow and understand. I also liked how you explained the purpose of an profile, I agree that it does demonstrate your work experience and helps build opportunities for professional connections.
Week 2:
-An Entity Relationship Diagram (ERD) is a flowchart (different than a swim lane) and it illustrates entities such as people, places, objects and concepts and its attributes and the relationship between them.
-The two notions for ERDS are Chen and Crow’s Foot.
-The primary symbols for entity is a blue rectangle, For attributes the primary symbol is a yellow oval. For relationships the symbol is a grey diamond.
-In a crows foot, the relationships are as follow: ,one to one, one to many, many to many. A one to one is closed both ends, a straight start and finish in a way. One to many is one of the ends being open and the other one closed. Many to many is both open end relationship for many possibilities.
-Key things for ERD tables are that they are composed of three main element (entity, attributes relationships). The entity is shown on the top of the list in the box (it is the unique identifier) and attributes are next on the list.
-Salesforce is a cloud based software that business use to help save leads, fin prospects, close deals. Salesforce stores data such as leads, tasks, accounts, notes and all team members can view.
-A dynamic dashboard is a type of data dashboard that always updated automatically. In salesforce you are able to create dashboards that allows other to access it as well.
-Three types of cardinality are the relationships; one to one, many to many, one to many.
-Your digital identity is who you are on the Internet. Everything you ever entered into the intreat is your what made digital identity.
-It is important to have a good digital identity because everyone can always look you up. All of your social media posts and etc. Especially in the professional world for example when employers look you up.
-The MIS community platform has all of coursework, lets us intercut with the whole mis community regarding any questions. We can collaborate, exchange info, post blogs and access homework assignments.
-It is important to build an e-portfolio because you can share all of your work with others and network.
Hi Adelina, I like your answer of why it is important to build an e-portfolio. I also believe it assist in reflecting on progress. LinkedIn is a wonderful e-portfolio tool. You did a great job answering these questions and providing a better understanding.
Hi Adelina, I agree with what you said about having a good digital identity, I think it’s very important to make a good impression, especially in the business world. The more information you have about yourself than the more business your making and the more money you are earning.
An ERD is a visual presentation of data that describes how the data is related to each other.
Chen’s Database Notation and Crow’s Foot Database Notation.
The primary symbols are a rectangle represents an entity, and/or noun, a circle represents an attribute and/or adjective/characteristic, a diamond represents a relationship and/or verb.
Crow’s foot notation relationships are one to one, one to many or many to many. A customer to a zero transaction or a customer to one transaction.
Three key ERDs regarding tables are entities, attributes, and relationships. Entities are represented by objects, person, concepts, or events.
Salesforce is a cloud-based company that is used worldwide by industry 100 businesses for marketing, sales, customer service, in assisting with reaching their goals for growth, organization and increase in revenue.
Dynamic Dashboards provides access to multiple users and not just one user as well as being able to be used by one individual and another one who is logged onto the system. The dashboard also displays specific data needed by the users.
The three types of cardinalities are: one to one relationship, one to many relationships and many to many relationships.
Your digital identity is your personal information that’s on the web which is the data created from your online usage. You can manage your digital identity by using an encrypted connection, use a VPN to hide and encrypt your data, and changing your passwords periodically that are complicated.
It’s important to have a good digital identity because many services, and products, are used to access personal companies, governmental information, banking, and employers require you to access online systems as well as verifying who you are based on your online data that is kept on an individual.
The MIS community platform is the digital online page which students use to obtain their online videos, assignments made available by the professors for learning and communicating.
Hi Anna,
I think you did great answer the questions. I especially like your tips for managing digital identity. Before this class, I thought using a VPN was some super advanced technology that I’d never understand. Now, I’m definitely going to look into using one to manage my digital identity.
Hello Anna, I like your post and while I won’t pretend to be an expert in VPN’s or digital data, I’ve heard that most publicly purchasable VPN’s are really just as bad as going in unprotected. Apparently its something you’re capable (if you’re a real programmer) of making yourself, and these ones readily available for purchase are just as bad, because they still ‘have’ your data, and they then do what they want with it behind your back. So I’ve heard.
1. An entity relationship diagram (ERD), also known as an entity relationship model, is a graphical depiction of the relationships that exist between people, things, locations, concepts, or events in an information technology (IT) system.
2. The two notations for ERD’s are Chen’s database notation and Crow database notation.
3. For entity it’s blue rectangle- Noun: Shopper for example shopper, item. For Attribute it’s a yellow circle- Adjective/Characteristics for example item price. For relationship it’s a grey diamond- Verb for example buys.
4. In crows foot notation it is divided into three parts. 1st is one to zero or one relationship is expressed as closed on both sides. 2nd one to zero or many is expressed as one side is closed and other side is opened. 3rd many to zero or many is expressed as both sides are open.
5. Relationship example verb is written on the arrow. Entity listed at the top of the table. Attributes are listed under the entity.
6. Salesforce is a B2B organization that specializes in providing superior Customer Relationship Management solutions to their clients’ sales teams. It is well-known for its outstanding CRM efforts. Because of their robust Value chain, they are extremely important to both businesses and customers.
7. A dynamic dashboard is one that automatically refreshes with real-time data. When a project schedule or record is changed, any dashboard that relies on that information is updated. Every time, we get real-time information. This is distinct from non-dynamic, static dashboards, such as those created in a spreadsheet for an executive summary report.
8. The three types of cardinality are one to one, one to many, and many to many.
9. A digital identity is reusable digital evidence of identity issued by a trustworthy authority with a predetermined level of certainty. Updating our User Profiles and Accounts allows us to control our digital identity. By conducting a name search. We may learn what information has been published about us by researching our digital identity.
10. A solid digital identity is vital for safety since those who know your personal information can open accounts in your name. Alternatively, if they know where you live, they can find you. Not everyone on the internet is trustworthy.
11. A MIS community platform enables the creation of a safe and secure online environment in which members may communicate with one another and with the organization, exchange expertise, assist one another, and build useful networks. A community platform is software that allows you to construct an online community.
12. The process of creating an e-portfolio might alter our perception of ourselves. Creating an e-portfolio can help us become a better student, a deeper thinker, a more succinct communicator, and, maybe, a better understanding of ourselves as a person.
Satish, you did a great job at answering these questions. You’ve provided clear and concise answers and explanations for a better understanding. I think your point of conducting our own name search to see what’s been published is very important.
Satish,
I agree with you on your comment about how the MIS platform is a safe and secure community platform. I have never used this type of platform in an online learning environment before and it is very helpful, while feeling a sense of community at the same time.
Hi Satish, I like how you described the benefits of having an e-portfolio. I found it interesting how you put it in a non business aspect by saying that it creates a better understanding of ourselves as people. I also think that it also more easier to be organized with an e-portfolio account.
Satish, I like that you brought up the importance of name searches online. I remember this being one of the more significant things that we were told even in high school- to look ourselves up and see what others might see about us. I think that the process of creating an e-portfolio can also alter the perceptions that others have of us. It gives us a sort of control of what other professionals see of us.
ERD stands for Entity Relationship Diagram. It provides the flow of information and what data is needed in relationship to one another. The main notations in ERD are the lines between the entity. There can be a one to one relationship, one to many, or many to many relationships throughout the diagram also called crows foot notation or cardinality points. The primary symbols in the ERD are the rectangle representing the entity, a circle representing the attribute, and the diamond representing the relationship. There is a primary key in every entity; something that is specific to the entity requesting the information. This is called the Primary Key.
Salesforce is a customer relationship manager that can also provide statistics and help organizations make clear decisions on sales and marketing. It is also considered a dynamic dashboard that provides access to multiple users.
Social media considered your digital identity. It is your own personal brand that employers look at to see if you might be the right fit for the company. Through building an e-portfolio, employers are able to gauge what kind of person you might be.
Hello, Alexander. I really enjoy your comments on digital identity, especially how social media is considered our digital identity, and how it is our own personal brand that companies look at to determine whether we are a good match for the firm. It’s amusing how everyone has a different perspective on digital identification. I read a few posts, and everyone had a different take on digital identity.
Social media is just one facet of your digital identity. Other facets would be financial information such as credit history and past purchases. A digital identity really is your footprint online, from the places you go, the things you tweet/like about, to the schools you went to. This footprint is also how businesses can target a specific product to you.
1. An ERD is a type of flowchart that illustrates how entities such as people, objects or concepts relate to each other within a system.
2. The two notations for ERD’s are Chen and Crows Foot
3. Entity – Rectangle
Attribute – Oval
Relationship – Diamond
4. There are 3 different relationships in crow’s foot notation: 1:1, 1:m, and m:m. 1:1 is expressed as a one-to-zero/one relationship. 1:m is a one-to-zero/many relationships and m:m is a many to zero/many relationship.
5. Key things about ERD tables are the three components’ entities, relationships and attributes. These are connected by lines.
6. Salesforce is a cloud-based software company that provides customer relationship management software and applications focused on sales, customer service, marketing automation, analytics, and application development.
7. Dynamic Dashboards enables multiple users to access a dashboard that was previously accessed only by a single static user. This means that it can be used by a specific user alongside a logged-in user, and display data specific to both users accordingly.
8. The three types of cardinalities are 1:1, 1:m, and m:m
9. Digital identity is information used by computer systems to represent an external agent – a person, organization, application, or device. It can be managed by safeguarding your social security number and choosing secure passwords.
10. It is important to have a good digital identity because it ensures democratized access to services. It unlocks a range of essential services now available online, be them financial, Healthtech PR related or educational.
11. The MIS community platform is a student professional development and learning management system that fundamentally transforms how students, alumni, faculty, staff, and industry partners interact.
12. E-portfolios aid in metacognition by providing students a space to pause and reflect on learning and how to transfer it to future contexts.
Hi Ashana, I like how you included the one to zero or one relationship for cardinality. I also thought the way you explained a digital identity really interesting. It definitely helps me makes sense of digital identity. It is basically the identity your computer/phone/etc has given you based on the data they collected.
Hello there, Ashanna. I absolutely appreciate your perspective on digital identity. and extremely precise in maintaining our digital identities by securing our social security numbers and selecting secure passwords.
Hi Ashanna, I really liked how you explained what the Dynamic Dashboard is and how it is able to be accessed by multiple users after it was first introduced by a static user. Very great detail in explaining this!
1. An ERD, or Entity Relationship Diagram, is a visual representation of data, and it shows how they are related.
2. The two notations for ERD’s are Crows foot, which is like two squares with lists of attributes and a line to connect them. The other notation is Chen’s Database, which has shapes to symbolize different data types.
3. The primary symbols are entity, which is shown as a square in Chen’s Database. It is a noun, such as shopper; attribute is shown as an oval, and it is an adjective or characteristic, such as item price; relationship is shown as a diamond and it is a verb,, such as buys.
4. The different relationships in crow foot notation are 1 to 1, 1 to many, and many to many. You express these relationships with a straight line and a perpendicular line at each end for 1 to 1, a straight line with a perpendicular line at one end and three lines (crows foot) at the opposite end for 1 to many, and a stright line with three lines (crows feet) at each end to show many to many.
5. Some key things to remember about ERD tables is the three notations for crows foot, the primary symbols, and that a circle at the end means the valueis null.
6. Salesforce is a cloud based Digital Product Management tool. It enables and enhances business and is used by industry professionals across all functional areas of business.
7. Dynamic dashboards are ones that update with real-time data, rather than showing data that had been put in and saved at an earlier date. The function is many people can use it at once, looking at different data or the same data in a different way. Also, multiple users can add to it.
8. The three types of cardinality are one to zero or one, one to zero or many, and many to zero or many.
9. Your digital identity is the combination of all digital traces of your life, including social medias, purchase history, likes and dislikes, finances, etc. You can manage it by being private and secure, networking, keeping a good reputation by posting professionally, and more.
10. It is important to have a good digital identity because future employers will likely look before hiring you. In addition, this encompasses your personal brand.
11. The MIS community is a way to have social interactions, collaborate, and brand digitally. It integrates professional development, and coursework.
12. The purpose of building and eportfolio is to demonstrate experience with digital platforms for jobs. It can also help you manage your online presence and digital identity more closely.
Cassadi,
I liked how you mentioned that building an e-portfolio will show future employers that you have experience with digital platforms. I have never thought about that before, it would definitely be able to give you a competitive edge with future employers.
Hi Cassidi! I totally agree that keeping a good digital identity is important in future employment activities, employers have access to so much information now! Digital identity collects so much of someone and it is important to keep an eye on how much info you let about yourself online as it could be used or seen by so many people, especially prospective employers. You brought up a good point that keeping interactions and therefore your digital identity more professional can help as your digital identity does relate much to a personal brand.
Cassadi,
You have very good points on digital identity, but I would love to add on by saying that having a good look on the internet for your future employers. Letting them know who you are and what you have accomplished in the past before hiring you.

-The purpose of building an e-portfolio is to display what a student has accomplished thus far in their course of study, such as notable accomplishments, or how far they are along in their educational journey. This is also a good place to share a current resume, for the purpose of attracting prospective employers.
Hi Olivia,
Your answer to the question on dynamic dashboards really stood out because it focused on the multiple users aspect of having access to the data. The data is only good if users access it and make data driven decisions. At my job we have several dashboards in Tableau that are updated in real-time but not many employees know how to access it and rely on me to provide the data in an e-mail communication. Little do they know – I just have it set up similar to Max (from the labs) to auto send a report every time a certain threshold has been breached and at 2.5 hour intervals.
Hi Olivia,
Great explanation of digital identity, I liked how you described that it goes further than just media platforms. Your digital identity includes every source of data left by your digital footprint, many people don’t think about how much data they leave behind day to day.

Hi Brian,
When answering the question about primary symbols, I was not certain if the colors were significant more than the shape of the symbol. Does it need to be a blue rectangle? yellow oval or grey diamond? It would be a good question for next class for the professor to clarify. I did Google a few Cheng’s diagrams and they were various colors which lead me to believe that the colors don’t have much significance.
Would the two types of ERD notation be Chen and Crows Foot? Chen shows a entity as a rectangle, attributes as ovals, and a relationship as a diamond. Where as crows foot notation describes the type of a relationship; 1:1, 1:m, m:m.
*What is an ERD? 3.1 (Slide 4, 5)
Entity relationships diagram (ERD) is a structural diagram used in designing databases. It visualizes the major entities withing the scope of the system and the inter-relationships among these major entities.
*What are the two notations for ERD’s? 3.1 (Slide 10)
The two ERD notations are Crow’s foot and Chen’s nottaions.
*What are the primary symbols? 3.1 (Slide 6)
A rectangle is the primary symbol for an entity which are nouns (eg. shopper, item, etc.)
An oval is the primary symbol for attributes which is an adjective or characteristic. (eg. price, color, etc.)
A diamond is the primary symbol for relationships which is the verb. (eg. buys, sells etc.)
*What are the different relationships in crow’s foot notation, and how do you express those relationships? 3.1 (Slide 11-15)
The different relationships in a crow’s foot notation are 1 to 1, 1 to many an/or many to many. A 1 to 1 relationship is a horizontal line with a small vertical line crossing over on both sides. An 1 to many has a horizontal line with a vertical line on one side. Many to many relationship is a crows feet line on both sides connecting many relationships.

Raj,
I really liked your simple and easy to understand response on the purpose of building an e-portfolio. Putting in valuable information about various skills and accomplishments they have can be used well for any resume being made.
Raj, I liked your concise explanation of Dynamic Dashboards. I personally have never used a platform like this before this class, but it does make so much sense as to why it is so beneficial to many companies. The ease of access to information/sharing that information is really useful.
Hey Raj,
Good job on your post. I liked what you said about digital identity, I also think it is something that needs to be taken care of.
1. An ERD or Entity Relationship Diagram is a way to show how data in the process is related to one another and gives the viewer a way to differ from the entities, attributes, and relationships that data provides.
2. The two notations for ERDs are Chen and Crow’s foot.
3. The primary symbols are the entity (Rectangle), attribute (Oval), and relationship (Diamond).
4. The different relationships in crow’s foot notation could be explained as one to one relationship which is shown by a horizontal line with a vertical line crossing on one side. A one-to-many relationship is established by a horizontal line with a vertical line crossing with three other lines coming out of the other side. A many-to-many relationship is a line with three lines coming out of it.
5. ERD tables are the entities, attributes, and relationships. They are all connected by lines

Hey Mia,
I very much enjoyed your responses. I especially liked your analysis of one’s digital identity, as you provided strong insight. Notably, your point about employers having access to your digital identity is something that everyone should take greater consideration of;. You also provided greater information about ERD diagrams that I had not originally thought to include.
Great job!
HI Mia, digital identity is important I agree. Its a way for employers to see what experience you have and it’s important to post relatable experience that will benefit you and your career.
An ERD (Entity Relationship Diagram) is a visual representation of different data using connections that describe now these data related to each other.
The two notations for ERD’s are:
– Chen’s Database Notation
-Crow’s Foot Database Notation
The Primary symbols are:
-Blue Rectangle/ Entity= noun ex. shopper, item
-Yellow Circle/ Attribute= adjective/ characteristic ex. item price
– Gray Diamond/ Relationship= verb ex. buys
The different relationships in Crow’s Foot notation can be described as one-to-zero or one relationship, a one to zero or many relationship and a many to zero or many relationship. The one to one or zero can be expressed as having one option. The one to many or zero can be expressed as having some options. Finally the many to zero or many relationship can be expressed as there is an unlimited value of possibilities.
The key things in an ERD table would be the relationship the verb is written above the arrow that flows with the rectangles. Entity’s are always listed on top of each table. Finally attributes are listed under the entity.
Salesforce is a cloud-based software company that provides CRM services.
Dynamic dashboards allow multiple users to access a dashboard of a single user. Their function is to allow the user and others to view the dashboard or data together.
Three types of cardinality are one to one relationship, one to many relationship and many to many relationship.
Your digital identity is your online profile like social media accounts; it’s how you present yourself to the online community.

I like the way you described digital identity and the way to manage your digital identity. I agree it’s important to keep a clean and professional digital identity because people can judge you before they meet you.
An ERD is an “entity relationship diagram” used as a visual representation of different data using conventions to correlate data. With that said, there are two kinds of ER diagram notations, Chen and Crow’s foot. Chen’s database notation includes Entity which is represented by a blue rectangle, Attribute, which is represented by a yellow circle, and lastly the symbol that represents Relationships is a black diamond. Relationship lines in crow’s foot notation have two indicators to describe the cardinality and the modality of the relationship. Cardinality tells you the maximum number of times that an instance of an entity can be associated with instances of the other entity. Modality tells you the minimum number of times that the instance can be associated with instances of the other entity. A key within ERD tables is an attribute in ER diagrams whose values are distinct for each individual entity in an entity set. Salesforce is a company that makes cloud-based software designed to help businesses find more prospects, close more deals, and wow customers with amazing service. A dynamic dashboard is a type of interactive data dashboard that updates automatically in real-time. Cardinality refers to the uniqueness of data values contained in a particular column of a database table. There are three relationship types or cardinalities, one-to-one, one-to-many, and many-to-many. Digital identity is the information relative to the data path between relationships and products. It is important to have a good digital identity because it promotes a better relationship between consumer needs and product, in this case your identity is the product. The MIS community platform is a development and learning management system that uses information technology to solve business problems. The purpose of building an e-portfolio is to demonstrate a professional appeal and provide a justified background.

ERD tables – key things?
Key takeaways for ERD tables are the symbols and what they mean, the difference between entity, attribute, and relationship, the two different notations, and the how ERDs can be useful and in what situation.
Salesforce is an online based customer relationship management platform. Dynamic Dashboards is a function in Salesforce that allows multiple users to access a dashboard. The three types of cardinality are 1:1; a one to one relationship, 1:m; a one to many relationship, and m:m; many to many relationship. Your digital identity is information about yourself that exists online to represent an external agent.

Hey Kelli,
i totally agree with what you said about e-portfolio, I said something similar down too!
– According to the slides an ERD is, “a visual representation of different data using conventions that describe how these data are related to each other.” (MIS, Slides 4 & 5)
-The two nominations for ERDs are Chen’s database notation & crow’s foot database notation.
– The primary symbols are square for the entity, circle for attribute, & diamond for relationship.
Entity, Attribute, Relationship
-The different relationships in crows foot notation are a 1:1 – a one-to-one relationship, 1:m – a one-to-many relationship, & m:m – a many-to-many relationship.
– The key things are entities, attributes, and relationships.
– Salesforce is a cloud-based platform to hone your development skills.
-Dynamic dashboard is a type of dashboard that updates in real-time.
– 3 types of cardinality are one-to-one, one-to-many, and many-to-many relationships.
– A digital identity is your footprint on the internet. Essentially what comes up when you’re googled. You can manage this identity by updating your security on certain things to protect your identity.
– It’s important because it’s essentially your firdst impression for interviews and prospective business ventures. It’s one of the first things people can judge you on.
– The community platform is a platform for MIS majors at Temple to connect with each other and share opportunities. It’s also a place for class activities and syllabi.
– The purpose is to create a place for future employers and business partners to see what footprint you have online.
Week 2 Questions:
1. We are using Salesforce to learn the mechanisms of this platform so we can then use it to determine customer behavior, response and reactions to different marketing strategies.
2. Specific to this course, we are using Salesforce to act as a Digital Product Manager in Max Labs. The benefits of creating a database include things like “trustworthy reporting, proactive service, simplified collaboration”, etc. Salesforce has made it easier to input and store customer information.
3. A circle is the starting and ending of an event. A rectangle represents the activity of a process. A diamond represents decision-making of a process. Arrows show the flow of the process. A cylinder represents stored data and information.
4. Process Mapping is a visual representation of the breakdown of a process. We use process mapping so we can be precise and accurate and look for solutions to a problem.
5. One mistake in this swim lane diagram is that “Place Order” should start with a circle since it is the beginning of the process. “Finish” should also end with a circle because it is the end of the process. “Deliver” should be a rectangle instead of a cylinder because it is an activity. Finally, “Finish” should be placed at the bottom of the diagram in the “Finance” section.
6. One benefit to swim lane diagrams is that it determines who does what and in what order it is being done. Another benefit is that it is a training tool for people to make sure the right steps of the process are being taken. Swim lanes can also be handed off to a computer, HR, etc. to be reviewed.
