This document contains source code for a computer shop management system project. It includes functions for adding, modifying, deleting, and searching computer product records in a database. It also contains functions for generating sales invoices and reports. The main menu allows selecting between product management, sales/purchases, and reports generation. Overall, the source code provides a way to manage the entire operations of a computer shop using a database to store product and sales information.

5. INTRODUCTION
The Computer Shop System is designed & developed for a computer shop to manage their records
of selling and purchasing of the computer parts from the dealers and sell them to the customers.
This system makes the work of the computer shopkeepers easy as it keeps all the records of the
computer product and also keep the records of the product that is sold to the customers. This
system first checks the availability of the computer parts and their quantity then enter the record
to the record table after deducting number of the computer parts from the quantity and then print
the invoice after adding all the discounts and VAT% and save the record for future use if needed.
It also prints the reports in a tabular form as well as according to the search of a particular
computer product available at that time, if product is less than it provides the facility to modify
the product by adding more. It automates the Systems records, their Selling and Maintenance,
Balance evaluation, due to calculation other functions. In other words, you can say it a complete
computer-shop management System. In this project we can easily maintain systems sales details.
We can see the Systems details before selling the particular items.
