ABC Video Shop plans to develop a video rental system. This system allows Video Shop employees to enter and store details of all videos / movies in the video file. The system enables members to enter required videos / movies and rent videos / movies, if available in store. All the videos / movie rental details will be stored in the rental file. Then the system calculates the invoice amount for the rental video / movies and sends the invoice amount details to print the invoice / receipt. Now the system will print the invoice and issue it to the member, and the members will pay the invoice amount and settle the transactions.
