I m a CS student and I want to make a project on java swing for generating Electric bill. So, database has to be maintained. For this i have to make my interface to communicate with sql for executing it's commands. So, how can i make this possible? Is the same possible with MS acsess? Which is simpler? I want to complete my project soon. please guide me...

Thank You...

Breakdown your requirement into simple steps. First of all you have to decide which DB is to use. My suggestion is SQL DB. Much faster in processing, much reliable.

Then you must design how you want to use DB. How to initiate/start the interaction with the DB.

Finally you can start work on with the application UI and the background process.
