Well.
I have installed derby plug-in, and the squirrel-sql for navigating.
I looked at those installations, tested them, understand them, and they
seems fine to me.
(Maybe I need to test some more DBs, but it may take time for testing many
...)

I just want to make decisions for using one kind of database that's is
freeware.

I got confused.
David said Derby has problems and is not supported
(Also at link : http://www.profectus.com.au/ee_freedbms.html)
and MySql for some versions is not realy freeware
(It is not quite simple to read every license agreement,
when I see the download to be freeware, and in little words it is not ...
if the license declare it is freeware - so it should be one. Isn't that so ?
Maybe I'll hire a lawer).

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

I need to decide what's best, with no obligation to the software for the
neer future
(and open office is freeware, with some reports tools, which I need.
I don't want also to write to specific platform,
so I need that the db should work on any kind of platform with some
adjustments - OS, Windows, Linux, etc ...)

Thanks :)
