- Make use of Windows Presentation Foundation (WPF) to develop a Stock Management System thatwill manage the items being stocked in a warehouse. The application has 3 modules named: Addproduct, List Product, and Print Bar Code.Add Product:This module is used for adding new products to the system. It will require some basic details likeProduct category, Product Name, cost price, selling price, quantity and bar code. The details willbe saved into a SQL database named StockSystemdb. One other interesting feature of this systemis the alert system.You can set a particular quantity for each item. Now a notification or alert will be given to the userif a particular item’s quantity gets below the set quantity. This will help the user in gettingnotifications of the items getting low in stock.List Product:This module lists all the items present in the database of the Stock Management System.
