[DUG] Suitable Database for XE2 Pro

That is correct - as long as you don't distribute MySQL together with your
product then the MySQL is free and your application doesn't fall under GPL
share you source restrictions. The MySql client is the exception of that
rule and can be included with your product without it falling under GPL
share source restrictions.

 

If you want to embed MySQL directly into your software then there is an
embedded version of the database that allows you to run the server inside
your application, without having to use network libraries or anything to
access the data.  This requires either a commercial license of MySQL  or
that you release your product under GPL with complete source (MySQL is
distributed under two licenses - GPL and a Commercial License).

I think the Postgres crowd would disagree with you there :-) Remember MySQL
being GPL means you can't ship it with your app - unless you open source
your app or pay for MySQL. Both Firebird and Postgres are the only two
"main" fully open source databases.
