If you want to create a new page for developers, you should create it on the Moodle Developer Resource site.

Talk:Database schema introduction

From MoodleDocs

I don't think adding the column information to this page is helpful. It makes the page much longer, and so harder to see the overview. This information is also going to go out of date really quickly. If you want to know this, look in Admin -> Development -> XMLDB -> DOC, or look in your database.--Tim Hunt 01:19, 15 May 2013 (WST)
