MySQL's license has strings attached, you can't use it for free if you don't want to release your source. Postgres has a BSD style license I believe, so there's no requirement to release your sources if you incorporate it in your own apps. People should always consider Firebird in addition to MySQL and PostgreSQL. Firebird's advantages are that it has a smaller footprint than both, has good concurrency features (it had them before Postgres), works well on Windoze and Linux just like MySQL (but also on MacOS X and quite a few other platforms) and may be friendlier/easier to work with than Postgres (although this is just a hunch on my part) and also has 'full SQL' features - subseects, views, triggers, SPs, RI, multiversioning concurrency, etc... Its cons may lie in the fact that it is not as fast as MySQL on simple queries, nor is its SQL dialect as friendly (esp. for web apps) - but nevertheless still pretty easy to pick up (just watch out for the casing gotchas). The one feature it doesn't have that Postgres does is Object Relational, but I don't know how useful that is for real world apps. License-wise, Firebird uses a Mozilla style license which as I understand it means that you only have to release source on those parts you modify which have to do directly with Firebird. Seems that in most aspects, Firebird is in the middle wrt to MySQL and Postgres. _ Philippine Linux Users Group.
