commercial

Hi SO,

I'm running a commercial(closed source) Web App development for the first time. Initially I considered MySQL the most feasible option for a DB, until I get quite confused about its dual license behavior.

If I want a commercial application do I still can use the GPL version of MySQL or I must get a license? The same question in a different way: If I use MySQL's GPL version does that force me to license the whole app under GPL?

Either case I would go with PostgreSQL, I just want to make really really sure about this. Even in SO I've seen related("duplicates") questions but never a clear answer...

All other tools I'm gonna use to code the project are licensed under BSD or MIT.

Just in case, the role of MySQL in the project is merely as relational DB to store persistent data and query it.

I'd really appreciate if someone can clarify this for me.

Regards, thanks in advanced.
