An ERD also has specific shapes, symbols, and arrows to describe the diagram. They are used to understand how a database system is going to be  structured.

  Database: A database is a place where collections of information that can stored and accessed by users. Furthermore, it can be accessed by many users. Moreover, it can be spread out to many locations (Beri, et al, 1989). What is a Database from my understanding: A database is a place where information is stored. Furthermore, it can control who accesses and edits the data. In other words, it is like a library for data. Advantages of Database: Increases the amount of users that can access the data.

  Hello, in this blog I will be documenting my progress on creating a customer database. Furthermore, I have used MS Excel to create it. Adding to that, MS Excel is famous for creating wonderful and organised databases and having all the needed tools to create it. My Progress: 1- I started by writing the title of the database. All I had to do is click on one of the cells and start typing. 2- I changed the colour of the text to red.   To do that I clicked on 'Home'. Then I went to the 'Font' section. After that I clicked on the letter 'A' that says font colour when you place the arrow of your mouse on top of it. 3- I then wrote the headers of each category. I also made the text bolder. 4-After that I started inserting all the information that was needed. 5- Finally, I added borders around it to make it look better. And that is the final look.

  Software Development Lifecycle:  SDLC is used to create and build software. SDLC, also known as software development lifecycle, is a cycle involving several phases. It can be divided into six stages: planning, defining, designing, development, integration or testing, and installation and acceptance (Ragunath, et al, 2010). Methodology of SDL: According to Scroggins (2014, pp. 21-22) the  methodology of SDLC is cyclical. In other words, the design of the software can be changed during any phase. For this reason, SDLC is considered flexible. Moreover, understanding the type of methodology is important since the process towards each phase can differ. Benefits of SDLC: Some of the benefits of SDLC are creating the structure of the software and saving time. In addition, it can be helpful when a staff member quits. Moreover, it brings up questions and errors that might occur later. Lastly, it allows the project to go through the time needed to be perfect. (Azat, 2022) Key sta...

Introduction: In this blog I will be analysing and comparing different product pages from websites. I have also chosen websites that sell clothes since I am creating a similar website.    White Fox boutique: This product page is quite simple. Both the description and image are available and in good quality. And the description is short and simple. Also, you can easily navigate your way through the pages. Furthermore, this website has different categories. In addition, you can see the prices of the products and the different colours that are available. Overall, this is a good product page and very straightforward. ZARA: Although Zara's homepage appears attractive, many people complained that shopping and browsing the website were difficult. First of all, the size of the description is small. Furthermore, it can be a bit challenging to find what you are looking for. Also, it seems to appear that they are cramming several product images in one row. On the other hand, the colours ...
