How to drop/alter a table in SAP DB

Hi,

I have created a couple of tables for testing in SAP DB using Java Dictionary. I am sure there is a way to drop any unwanted tables in SAP DB like other database, but just could not find a way to do it. Is there a tool to perform this task?

Appreciate if someone can clear my doubts on this database maintenance problem on SAP DB. Any link to a reference document will be great. Thanks!
