• Briefly describe on the project:

  • The project is about building a CLI app, that simulates some functionalities of Digikala (A very popular e-commerce website).

• objectives of the program:

  1. This program should provide an easy a user-friendly interface for all three objects (Sellers, Buyers & Admins), that are using Digikala.
  2. The program should be able to handle all the shopping processes like Wallet Charging, Managing Shopping Cart and so much more...
  3. After shopping, the money should be automatically deposited to the Shop's wallet and also the Seller's wallet.
  4. And all that you can except from a CLI Digikala app :).

• Provide a high-level overview of the approach taken to complete the assignment:

  1. At first it's good to have an intuition on the functionalities of Digikala, and how things should work under the hoods.
  2. The second part is to try to implement objects and interfaces to work with to let the program and shopping processes work, Of course this is a really important part of programming to see what you have to do and decide how to implement the stuff .
  3. Last but not least is about linking the UI to the code bases and functionalities.

• A brief description of the design of the solution :

  1. First we declare some category and subcategories to cover a wide domain of products that exist in real life.

     Here you can see diagram of my UML design for product, categories and also subcategories : UML Design of Products, Categories and Subcategories

  2. Then we have to design classes for each entity Admin, Seller and User.

     Here you can see diagram of my UML design for Admin, Seller and User : UML Design of Admin, Seller and User .

  3. After declaration of class user, we have to define some entities related to shopping, such as Order, Shopping Cart and Wallet Request to track shopping processes of each user.

     Here you can see diagram of my UML design for Order, Shopping Cart and Wallet Request : UML Design of Order, Shopping Cart and Wallet Request .

  4. At the end corresponding to functionality of each entity we define our Shop class.

     Here you can see diagram of my UML design for Shop : UML Design of Shop.
