Thread:Project:Support desk/Using transclusion to stop database growing huge?

Hello. I run the Logic Museum http://www.logicmuseum.com wiki. This uses some very large pages consisting of very large parts which don't change very much, with short introductions that do change quite a lot. When I edit the introduction, this adds the whole text to the version history, so the database goes up by 250k every time (for example). Can I stop the database growing so much if I put the large stable part into a separate file, then transclude the large file into the introductory file? Or does the database grow everytime I edit a file that includes a transcluded one? Thanks for any help.
