What is an ERD? 2a

Montajim Khan - February 27, 2023 1 Comment

Entity Relationship (ER) Diagram Model with DBMS Example

ERD, also known as Entity Relationship Diagram, is a visual representation of different data to describe how they are related. The two notions for ERD are Chen’s and Crow’s. Chen uses rectangles and diamonds to show a relationship, and Crow uses rectangles to connect to another rectangle to show a relationship. There are three primary symbols for ERD: entity, attribute, and relationship. The entity uses nouns, Attribute uses adjectives or characteristics, and relationships use verbs. The three crow’s foot notation is 1:1, which is a “one-to-one relationship,” 1:m is “one to many,” is to many relationships, and last is m:m, a “many-to-many relationship” this help describe the characteristic of the relationship between two entities. I think the key thing of an ERD table is to label if you don’t label your boxes and lines, you might end up lost. Or make sure you’re using the right Chen’s or crowfoot notion for your ERD table.

What is the purpose of a CRM?

Yi-Lun Ma - February 27, 2023 1 Comment

Customer Relationship Management(CRM) is a system to help a company’s business managers interact with customers, streamline processes, and improve the relationship with the customers. To improve the relationship with the customers, the CRM system can help the company track customer interaction, preference, and feedback, which can that the company know what part of the service needs to strengthen and provide better service for the customer.

  1. Increase efficiency: CRM can save time for the repeat question, for example when you email the company about an issue with the product, most of the time the email will repeat automatically, so the company can save time to help those people on higher-value activities.
  2. better collaboration: CRM can organize customer information and communicate more effectively and work together on customer projects. To increase teamwork and productivity.
  3. CRM is usually used by any company, such as sales, marketing, customer service, and support teams. Not only for those small companies but also large corporations can get benefit from CRM.

 

Why Salesforce Benefits Us? 1b

Montajim Khan - February 27, 2023 1 Comment

File:Salesforce.com logo.svg - Wikipedia

We’re learning salesforce in this course because it will look good on our resume and helps companies with customer relationships and customer service. The benefit of creating a salesforce database is that it helps with time management, planning, customer satisfaction, and revenue increase. The list goes on to explain why creating a database in salesforce benefits. As a marketing major. I quite enjoyed learning about Salesforce because all my professor spoke about was Salesforce which I had no clue about till we did Salesforce in this course. I was happy because I could see myself using this in the future. CRM (customer relationship management) is an important part of learning about Salesforce. If your customer isn’t happy with how the company handles things, fewer people would be business with you. An example is if you forgot your customer’s name, it would look bad, versus if you told them a happy birthday, they would be happy. Keeping track of the smallest detail will increase customer satisfaction.

Important acronyms to know SDLC API ERP UX 1a

Montajim Khan - February 27, 2023 Leave a Comment

Important acronyms to know are SDLC-Software Development Lifecycle, API-Application Programming Interface, ERP- Enterprise Resource Planning, and UX-User experience. SDLC can be used in technical and non-technical areas. Examples would be software and hardware. It helps structure steps that are involved in the system. API is software components “that automatically update data between clients and servers.” API examples are “data sync to the cloud” and “Automatic sync timezones onto your laptop.” API is beneficial because of integration with pre-existing code. Innovation because it’s quick and easy to change things. Expansion can be on all platforms like phones, computers, etc. Lastly, it’s easy to maintain. ERP pretty much helps businesses maintain time, such as organization and planning. Integrating into a company helps data get to the user in real-time.

What is the purpose of building an e-portfolio?

Yi-Lun Ma - February 27, 2023 Leave a Comment

Why did we need to build an e-portfolio?

First, in the portfolio, we will put all of the things digital, such as work, accomplishments, skills, and experience. E-portfolio show individual learning, growth, and development. The reason why we build the portfolio is that all of the people have different personal goals and different circumstances. What place do we need to use the portfolio?

  1. Career development: some companies hope you have work experience, so we need to build a portfolio to show to our personal strength to the company. It also can be used to present a person’s work to potential clients, employers, or collaborators, making them stand out in a crowded employment market.
  2. Personal Development: you can change your portfolio at any time, so some people will use this tool to be a reminder that be used to a reflective tool for personal growth.
  3. Academic Assessments.: In modern times, most of the homework is published electronically. Students will use the tool to demonstrate their understanding of the concept and get some feedback from the professor in convenient ways, without using the paper.

 

About Salesforce and Swim lane

Yi-Lun Ma - February 27, 2023 Leave a Comment

Why a salesforce is a good tool for businessmen?

First, Salesforce is a customer relationship management solution that connects companies and customers. Salesforce is an integrated CRM platform that provides all your departments, including marketing, sales, commerce, and service, with a single, shared view of all your customers. Salesforce can also build your own website and share reports with your customers about the company’s performance. If you want to businessman, I strongly suggest you learn about the coding language and the application. Second, Swim lane is an excellent tool to help you certify everything in a clear way. Just like exam 1 and exam, you can put a whole paragraph into the swim lane. Then you don’t need to look all over the whole story and you can know what it wants to tell us. Last swim lane can help you label the thing you will do next and if you accept “yes” you will go to the next step and if you say “no” it goes to the end.

Talk about the important acronyms, including SDLC, API, ERP, UX

SDLC: Software Development Life Cycle is referred to as SDLC. High-quality software is designed, developed, and tested using this approach, which is utilized by software development teams. Planning, design, implementation, testing, deployment, and maintenance are some of the steps that the SDLC includes.

API: The application Programming Interface is referred to as API. It is a collection of procedures, instruments, and conventions for creating software programs. APIs outline the interactions and communications that should take place between software components.

ERP: Enterprise resource planning is known as ERP. It is a piece of software that businesses utilize to run their daily operations. ERP systems combine numerous corporate processes into a single system, including finance, human resources, supply chain management, and inventory management.

Protecting Ourselves from Hackers (4b)

Sophie Chen - February 27, 2023 4 Comments

Threat modeling is when the user thinks about who would potentially try to breach data to better protect it. It reminds me of how detectives will try to solve a case by putting themselves in the suspects’ shoes—they try to think like the suspect in order to predict what moves the suspect would make. As technology becomes more and more of an essential part of daily life, data breaches and cyberattacks are quickly jumping the list of the most likely global risk, trumped only by natural disasters and extreme weather events.

Ransome ware is malware that locks a computer to prevent the user from accessing data until a ransom is paid, typically in Bitcoin to prevent tracing. It is extremely effective since the hacker can tailor the hack to make it personalized and harder to crack, almost like creating a custom key to unlock the malware. It is often installed on a computer through tainted website links or clickable downloads. Hospitals are extremely susceptible to ransom ware due to the immediate need for up-to-date and accessible data. They cannot afford to shut down while they try to remove the ransom ware and will often give in to what the hacker wants in order to be able to access data again.

It’s important to back up your data often to prevent it from being lost, whether to a hacker or other. Also, you should never click suspicious links, and definitely do not download software that you don’t fully trust.

The Cloud and Network Effect (4a)

Sophie Chen - February 27, 2023 1 Comment

The network effect happens when the value of a good or service rises as an indirect effect of more people using it. There isn’t always an obvious change, but it is not purely coincidental that platforms that start to gain more traction also start to earn more money. A good example of this is Facebook—Facebook started to grow and evolve as more people started creating accounts and using Facebook, thus also adding more data. Facebook began earning more money as it collected valuable information about customer preferences and running ads.

Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Cloud computing has become very popular in recent years due to the rise of technology—with so many people able to access the internet and data from their own homes and smartphones, it is easier to store all information in one central place that is conveniently accessible to those who want to find it. Unfortunately, since all the information is stored in one central place, this can bring up issues of safety and data breaches since all the information can be accessed from one location.

API stands for “Application programming interface”, and it is a software intermediary to allow two applications to communicate with each other. Building APIs onto older systems makes it possible for businesses to extract valuable existing data for new innovations. Incorporating APIs into new applications allows easier consumption and reuse across new web and mobile experiences.

Similarities and Differences between CRM and ERP (3a)

Sophie Chen - February 27, 2023 1 Comment

ERP stands for “enterprise resource planning”; it’ purpose is to standardize, streamline, and integrate processes across a wide range of business functions. Essentially, ERPs help manage business process and finances by integrating all necessary processes into a single system. Legacy systems may run into problems sometimes because it is often hard to keep everything running at a fast and efficient pace. Also, there may be issues with security since all the data is in one place. As companies begin to expand and try new technologies, legacy systems are slowly becoming outdated or incompatible with new technologies. I liked this resource (https://www.bairesdev.com/blog/7-problems-with-legacy-systems/) if you want to learn more about legacy systems.

CRM stands for “customer relationship management”; its purpose is to manage a company’s interactions with current or potential customers. A CRM system can span across an entire enterprise’s infrastructure, and CRM systems can link up information about current or potential customers. CRM software should be viewed more as a strategic process to understand customer needs rather than a platform. Salesforce is one of the world’s most trusted and used CRM platforms. In Max Labs, we designed a software for Riley to keep track of all her potential investors, including contact and company information, meeting notes, investment amount, and past and future meeting dates. We keep designing our platform to be more efficient for storing information, and our data could be accessed from all users in the company.

CRM and ERP are different in the sense that CRM focuses on sales force automation and converting leads into contacts while ERP aims to coordinate the process of producing and delivering products to consumers. ERP manages financial information about sales. CRM keeps track of the contacts who ordered the products. ERP and CRM serve different purposes but ultimately work towards a shared goal: to increase company information organization.
