What is "best"?

robert

Actually, could someone tell any embedded open source database
products names?

Cheers!

By "Java embedded DB", I assume you mean a DB which can be run from
within your java program, as opposed to a seperate process. I'm assuming you
DON'T mean a DB for embedded devices (e.g. cellphones).

I've used HSQL and am generally satisfied with it. The DB can be
entirely in memory (and thus non-persisted), or persisted to disk in various
formats.

Apache Derby seems to be the big player these days. It was originally
produced by Cloudscape in around 1996/7. Cloudscape was taken over by
Informix. Informix was taken over by IBM. IBM have passed it onto Apache
(but still use it as a basis for their commercial Cloudscape product).

Derby is more mature than HSQL, more scalable, is more complete and has
sensible defaults. It also appears to be backed by Sun as well as IBM.

I don't know who is the best for your application, but for a list of
them, see http://mindprod.com/jgloss/sqlvendors.html

I second that!

Yes. I just mean it

How about Berkeley DB?

Everyone assumed assumed that by "DB" you mean SQL. BDB isn't,
but if your application is happy with hashes -- sure, by all
means.

In that case serializing Maps to files could be an option, too.
