Database for dynamic tables to be accssed through Java

[Pratik Lohia]

I want to create an application in which I need to create new tables from my JAVA program as per customer request. The DB should be light weight, as my application is a client application running on stand alone computers

Derby is more popular, but I believe Berkeley DB to more powerful.
