Package Structure

Class Definitions

Entities

Customer

class Customer{
    id: Long
    name: String

}

Data Access Objects

ICustomerDAO

interface ICustomerDAO {
    Customer add(Customer customer);
    Customer findByID(Long customerID);
    Customer update(Customer customer);
}

IItemDAO

interface IItemDAO {
    Item add(Item item);
    Item update(Item item);
    Item findByID(String itemID);
}

Service Layer

ICustomerService

interface ICustomerService {
    Customer findByID(Long customerID);
    Customer createCustomer(name); //create customer and their account also here
    Set<Item> itemsBoughtByCustomer(Long customerID);
    Customer addAmount(Long customerId, double amount);
}

IItemService

interface IItemService {
    Item create(Double price, String description);
    Item findByID(String itemID);
    Item buyItem(String itemID, Long customerID);
}

Tasks to be done

Sprints

• Sprint 1: Setup boot, JPA container managed transaction project.

• Sprint 2: Create Customer module without items module (skip relation part) using layered architecture. In console UI, print customer add(), find() operation outputs.

• Sprint 3: Create Items module (skip relation field with Customer part) using layered architecture. In console UI, print items add(), find() operation outputs.

• Sprint 4: Add relationship between Customer and Item. Improve the part where Item is to be saved with Customer now. Check if relationship is working by printing details of item and it's customer, and customer with all the items he has bought.

• Sprint 5: Open REST endpoints for customers.

• Sprint 6: Open REST endpoints for items.

REST endpoints

Open REST endpoints for the following operations:

1. Get customer details by ID (customer ID, name, account ID, balance).
2. Get item details by ID (item ID, price, description, customer ID, customer name).
3. Endpoint for customer to buy item.
4. Find all items bought by customer.
5. Add balance amount to the customer's account; the REST endpoint should accept customer ID and balance in PUT request.
