I don't know whether it is right place to post. I am learning Servlet, JSP. Whether is there any online database, we can use it, without downloading and install it to the machine. For example I want to add(retireve,update,delete) a record to(from) database using MVC arch.
There are none I can think of that are free. If you pay for web hosting, you usually get database space. But easier than that is to download an open source RDBMS. You might consider HSQLDB, whic is good for development and testsing smaller apps.
I'd use Access only as a last resort. Its a poorly designed and implemented "database" which will give you some awkward problems.
