David said Derby has problems and is not supported


No surprise in that. Support 8x5 or 24x7 always cost money.

You can buy a commercial product or find someone that are
willing to support Derby if that is a problem.

Neither SUN nor IBM want to provide free support.

and MySql for some versions is not realy freeware


It is open source.

It is free for anyone that can accept the GPL license
with FLOSS exception MySQL use.

The very short version is:

you do not distribute your code outside your own company => no
problem

your code is open source => no problem

else => you need to consult with lawyers whether you need to
buy a commercial license or not

If you buy then you get support as well. And that support
may be worth all the money if it is production.

Also for first time making db with about 150 tables,
for commercial use in about a year.


GPL and all other open source does not really distinguish between
commercial and non-commercial. The distinctions goes between open
source and closed source and distributing to external entities or not.
