How create API for DB application.

Hi,
I have created one DB application, through this we can insert data in the DB table.
Now, i want to create an API for this application. By importing this API we can use this code anywhere.
Therefore, can you please help me to create this API ??

Thanks,
Ashish

What features should this API have that JDBC doesn't provide already?

Hi ulf sir,
Actully our parent company wants only API. thats why i want to create API for DB application.

JDBC is a database API. If they want an application-specific API then they need to specify what it should do (and check with you first that whatever they require is actually possible to do).
