LAZA

E-commerce is booming and you are tasked to design the database for a new online shop LAZAGA. LAZAGA sells everything from high-fashion to daily necessities. Whatever you can think of, LAZAGA sells it!

Here's what you need to do:

• Draw the ERD (you can use tools like https://www.draw.io/ or https://www.lucidchart.com/pages/)
• Create the SQL for tables and columns
• Write SQL queries to get information

Users should be able to login, view the catalog, add items to cart and checkout.

You will likely need to change your tables as you expand and add more features. You will need more than 4 tables, excluding users, as a start
