>And if I don't distribute MySQL for my application and just make a module to create the data structure? I will need to distribute only the ODBC driver. And I will ask the user to install a MySql server. There are a lot applications distributted like this.

If your application is not under GPL and you distribute ODBC driver, you also need license for ODBC driver .

From MySQL license policy page :
3. Commercial use for everyone else
If your application is not licensed under GPL or compatible OSI license approved by MySQL AB and you intend to distribute MySQL software (be that internally or externally), you must first obtain a commercial license to the MySQL software in question.
More specifically:
a) If you include the MySQL server in your non Open Source application, you need a commercial licence for the MySQL server

b) If you include one of the MySQL drivers in your non Open Source application (so that your application can run with MySQL), you need a commercial licence for the driver(s) in question. The MySQL drivers currently include an ODBC driver, a JDBC driver and the C language library.

c) If you use MySQL Software within your organisation and you don't want to risk it falling under the GPL license, you are welcome to purchase a commercial license.



>I think mysql and Postgresql are both good solutions.

Don't forget Firebird SQL. It is 100% free, even for commercial distribution, has a lot of advanced features (triggers, stored procedures, views, server side cursors, foreign key constraints, subselects, online backups, database shadowing, MVCC engine - reads never blocks writes, etc.) and it is fast (not as fast as FoxPro, of course :) .
I've started to use it and I like it.
