Thread: How do I save organized data and store it locally?

I'm not pretty sure whether this forum is correct one, but anyway.
I'm writing program, that will allow user to rate certain content and store this rating information locally. An intuitive example of such an info:

Tag Likes
tag1 4
tag2 5
tag3 0
...
tagN M

Of course, I can just write and read that info to and from file using streams. But I'm curious whether there are some more convenient methods to store such an info? Maybe something analogous to MySQL databases, but local variant, who doesn't need to be ran as a server? Or something like that. Any suggestions?

Derby is a smaller database option that is built-in to Java. Maybe try that.

Thank you, guys! Yes, it seems, that Derby is exactly what I need.
