Overview of the application: Sales Record System for a Departmental Store
We are going to assume the end user of this app is a wholesale dealer who wants to track in-stock product quantities, sales, and customer information. In this application, the user can store and track information about customers, such as names, e-mail IDs, and phone numbers, as well as sales data and product information (name, quantity, price, photo, and inventory). Therefore, the application must store information about:
- Products
- Customer information
- Sales
Note
From now on, we will be referring to a vendor's product as Master Product and an item sold to customers as Product.
