Hello It is required to post an SQL Database project ,a small one that consists of 5 relational tables for my graduation project.The tables should be some thing rather than Rep,Customer,Orders,Order_Line and Part.What I need is just an idea.
How about a HR application? Like apply leave online, overtime, claim request, talent management etc. These kind of projects are easy to understand but very helpful when applied in real company. Inventory management? Booking system? Hotel management? Hope it help
You may also have a look at Sakila MySql database: dev.mysql.com/doc/sakila/en/sakila.html maybe it will help you generate an idea of what to do
What you could do is a book store or a big data project. You could even use an ETL program to upload your data, customize an open source program to have a better performance with the program.
