Let's design an online retail store.

Amazon (amazon.com) is the world’s largest online retailer. The company was originally a bookseller but has expanded to sell a wide variety of consumer goods and digital media. For the sake of this problem, we will focus on their online retail business where users can sell/buy their products.

Requirements and Goals of the System

1. Users should be able to add new products to sell.
2. Users should be able to search for products by their name or category. 3
