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. http://hsqldb.org/ - Oliver >>Actually, could someone tell any embedded open source database >>products names? > > I've used HSQL and am generally satisfied with it.

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. http://db.apache.org/derby/ Tom Hawtin  SignatureUnemployed English Java programmer http://jroller.com/page/tackline/ Oliver Wong wrote on 11.01.2006 19:44: >>Actually, could someone tell any embedded open source database >>products names?

In that case serializing Maps to files could be an option, too. :-) robert On 11 Jan 2006 06:29:46 -0800, "huangjun2@gmail.com" <huangjun2@gmail.com> wrote, quoted or indirectly quoted someone who said : >what is the best embeded DB for Java Application?
