Scenario ByteFlow Technologies, the successful business from Lab 1, has made significant strides and is now looking to invest in the enhancement of their business infrastructure. With a diverse portfolio of products and services and recent funding secured, ByteFlow Technologies aims to allocate resources to develop a centralised system for streamlining their operations. As a crucial part of this endeavor, they are seeking to design and build an advanced web application that empowers administrators to efficiently manage products, plans, pricing, and clients. The administration section of the web application should encompass various functionalities, including the ability to add new clients, manage client details, add new products, update product information, set plans, pricing, and discounts, classify businesses, generate reports, and so on. To ensure security, the application should incorporate a robust login system for administrators, and all data should be stored in a centralized database. Furthermore, the application can offer B2B clients a flexible choice between self-hosting the application on their own servers or opting for a cloud-based Software-as-a-Service (SAAS) offering.

As an analyst/programmer/solution architect, your task is to design and develop the admin side this advanced web application for ByteFlow Technologies. The first phase of the project i.e., Lab Assessment 2, will involve requirement analysis, database design, and modelling (learnt in prerequisite course). During this phase, you will work closely with the company's stakeholders to gather requirements, identify use cases, and create a detailed project plan. You will also be responsible for designing the database schema and modelling the data, ensuring that the application meets the company's needs for scalability, performance, and security. The second phase of the project i.e., Lab Assessment 3 will involve full-stack implementing the of the application. Model Design Requirements You are going to design a model to store data for your application with the following specification: You have freedom to design your own data architecture and properties for the classes, however it should reflect your understanding about complex entity relationships, including onetoone, onetomany, manytomany, and inheritance. The application should store information for every class and relationship. Inheritance should be used to model classes with similar properties. For example, human being class may have common properties such as ID, Name, Contact details (email, phone, address, etc...). Besides, each unique class should also have its own properties. You should provide justification in your report, on the proposed classes, properties and their relationships stating why they are necessary. Appropriate data annotations and input validations should be provided in all model classes. You should customize your own error messages and NOT use the default error messages provided by the template.

To fulfill the requirements for assessment 2, you need to submit a report including the following contents: 1. E-R diagram for all possible classes you will use in your project. 2. Detailed description of the classes 3. List all possible views, controllers, and actions, with detailed description 4. Screenshots for all views and pages you have designed for this project. And you are also required to submit a zipped file with all source code you have done. You need to complete the following points at this moment: 1. Initialize ASP.NET Core MVC solution for this project

The question is the step by step explanation of the requirements and the implementation done separately.
