- What can you do to guarantee that your model has all it needs to function properly?Why might problem statements benefit from data modeling techniques?Explain the development of Use case and Use case diagram.Entity-Relationship Diagram (ERD) is one of the data modeling tools that provides a software engineer with the ability to represent data objects, their characteristics, and their relationships. Use an ERD to describe the following scenario. A teacher is identified by an ID number (TID), last name (LName), and first name (FName). A project is identified by a project ID (PID) and title (T). A student is identified by an ID number (SID), last name (LName), and first name (FName). A teacher can supervise zero, one, or many students and a student is supervised by one teacher. A teacher must propose one or many projects and every project is proposed by one teacher. A student must work on one project and every project is worked by only one student.
- Design a Requirements Traceability Matrix (RTM) for a program you familar.Convert the below ER diagram to class diagram by using Argo UML not hand write1 IntroductionIncreasingly supermarkets are introducing self-service checkouts. Your task is to develop a design for Easy Checkout, a new self-service checkout system. You should follow a function-oriented design approach, i.e. you should develop:1. a data flow diagram2. structure chartsYour design should focus on the processing of a single product. This will provide the foundation for the full design of EasyCheckout. Details on the requirements that you are to work with are given below.2 Informal Requirements for Easy CheckoutUsing Easy Checkout, customers take responsibility for presenting products to an optical barcode reader. Once this scanning process is complete for each product, the barcode is converted into the store’s internal product identification scheme. Customers place scanned products on a conveyor belt, which takes them to the packing area. Note that the conveyor belt also provides a weighing capability, i.e. the products are weighed in order to check that they match up…
