Problem Description The Operation Manager of a Karak shop keeps an inventory of food and beverages raw material, onpaper. The usual operations of the manager for the inventory database include adding new material, updating levels of current stock material and producing different reports based on the current stock levels. As the inventory is getting larger, this manual system is becoming difficult to manage. The Operation manager decided to develop a computerized system to help him manage the inventory to increase the effectivity and the efficiency of the shop Operations. Because the manager is not an expert in database management systems, he decided to develop his own application, based on the Python knowledge he had during his early engineering education.
