Sw-spec/ebook

In this project you will have to develop a simple e-book shop application.

Your work

• Implement the following functionalities (in phases).
• Before actual coding for each use case or feature, sketch a sequence diagram for it first.

Functions

• List available e-books
• Basic search functionality
• Basic account operations: check fund & add fund
• Buy an e-book
• Show list of user's e-books
• Refund (within 5 minutes)
• Basic book promotions

Goals

Phase 0

• List available e-books (with mock-up data repository)
  • The app should show the list of all available book titles with prices (from the mock-up data repository) in a list view with no book cover preview.
  • Implementation info:
    • Use repository pattern.
    • Create book repository class that returns mock-up data.

Phase 1

• List available e-books (real data)
  • The app should make an HTTP request to get the JSON book data (see below)
  • Implementation info:
    • Extract book repository interface from the mock-up one.
    • Create a real repository that actually makes HTTP requests. (Watch old clips on how to do that with AsyncTask)

Phase 2

• Basic search functionality
  • The user should be able to search for books by parts of the titles and publication years
  • The user should be able to sort the search result by titles and publication years
  • Implementation info:
    • The search functionality should be implemented in the repository class. It might be good to put the code in some concrete parent class that both the real and the mock-up repository classes extend.

Phase 3

• Basic account operations: check fund & add fund (all mock-up)
• Buy an e-book
  • A user can add e-book to the cart
  • A user can check-out all e-books in the cart. Don't forget to check if the user has enough fund in the account.
• Show list of user's e-books

Phase 4

• Show book cover
  • The image URLs are in the img_url fields

Phase 5

• Basic book promotions
  • Load promotion data and show promotions (see below)
  • The app should only show available promotions (ones where the user can only buy--i.e., if a promotion contains books A, B, and C, but the user has already bought book B, the promotion is not available to the user).
  • Buy e-books from the promotion.

Phase 6

• Refund (within 5 minutes)

Data

The book data was scraped from [1].
