Thread:Project:Support desk/Moodle and MediaWiki database integration/reply

Its very very difficult to say without knowing what exactly your planning (additionally I'm not exactly familiar with all of our future plans), but its unlikely we would do something that would obviously mess up such plans. The db schema does change from time to time (mostly in minor ways), but there hasn't been a total overhaul of it in a very long time (probably since MW 1.5), and I think its unlikely there would be one in the near future.

Again it depends very much what you are doing, but many assumptions that you will be making are probably of the same type that various extensions make, which we generally try to avoid breaking.
