Backend Administrative Tools

I am working on implementing the backend administrative functionality for the product showcase project. The database design and implementation is complete, the administrative tool will be used for the purpose of adding data to the database so I can proceed the actual showcase presentation functionality. Every table in the database has functionality engineered in the backend administrative area to manipulate the table, such as adding record to the table, deleting a record, or updating a record. If my database contains 50 tables; there will be 50 functionalities for each table just of data entry and data manipulation.
