Why do you want to develop a database when there are some good ones for
free?

If you don't develop one, how can you really know what a DB is?
If you don't develop one, all your theory that learnt from university
are still rubbish.

I don't have to be able to lay an egg to be able to tell a rotten one.

While hands-on experience may be better than theory *in theory*,
in practice it takes too much time and there are too many gritty details
to distract from the essentials. Theory is often quite sufficient.

Second, if you just want to learn how to do it, performance is
irrelevant, and ease of development everything, right? And that's
one of Java's strongest points.

And you have to develop an operating system to know what an OS is. Oh, and a
new internet protocol. Developing a new programming language and its
compiler is also much fun. In your free weekends you can develop an office
suite.
