There are five models in the project

• Suppliers
• Users
• Products
• Purchase Orders
• Sales Orders

All of them have it's own page with AngularJS CRUD implementation on the front-end

Stock depends on Purchase orders and Sales orders so formula is:

• Purchase Order Quantity - Sales Order Quantity

If I create a purchase order then Product's quantity will rise If a create a sales order then Product's quantity will decrease

This project is a test project therefore I did not use any database but I have a helper class with some test data in it.
