Drug Stores with quantities

Drug stores, is an app used by drug providers to store available drugs and their quantities.

When a drug salesman is asked for the quantity of a drug, from the drug store, he/she can use the app to get whether the requested quantity is available, and to make an order which consists of several drugs and their quantities.

The idea of the project emerges from a problem, usually when using paper to store quantities, drug salesman doesn't have an idea whether the requested quantity is available or not, he/she makes a promise to provide the drug with the requested quantity, yet he/she fails to fulfill this promise.
Now with the help of the app, he/she tells the seller immediately whether the quantity is available.
