Free database to use

Dear Friends,

I want to use a free database for my application built in Java. I don't want to use MySql since it costs for Runtime licensing.

So please help me in finding out a commericially free database for my application

thanks & regards,
raj

Firebird or PostgreSQL it's not that difficult

So you want to bundle the database with your program when you distribute it, right? Due to the GPL that does cut out MySQL.

PostgreSQL is still available since its released under the BSD license and is a great Open Source database system. It is Linux only though, they are currently working on getting a Windows version out.

Firebird is the Open Source release of the Interbase database system and is a great DB that can be used on both Linux and Windows. It is released under the Mozilla Public License (MPL) which I am sure does allow you to bundle it as part of a larger package.

SQLite is a really simple database package that is released under public domain and works under Linux and Windows. Its handy if you want a really lighweight database without all the bloat caused by unused features.

Does we have suitable driver available for firebird and PostGreSql? Also these db's are supported for all OS like Linux, solaris and Windows

I posted my reply just before yours

I have outlined which ones work for Linux and Windows, not sure about Solaris though. Suggest you have a look at their sites and see.

As for the drivers

PostgreSQL JDBC Driver
Firebird JDBC Driver
SQLite JDBC Driver

Thanks for ur info, actually after submitting my query only I have seen ur reply

Just edited the post and put in links to JDBC drivers for each one.

Thanks again for the help, I will try these dbs and find out which one is suitable for my application. From these three which one u think will give more performance, reliable, active usage and support, less in size.

If you have a small to midsize database, you might want to consider hsqldb (hsqldb.sourceforge.net) as well.
