maintain

Smartphone Experts own and operate a number of world class Smartphone blogs and communities (such as precentral.net and crackberry.com). We’ve grown steadily over the last few years and have reached the point where dedicated coverage is needed for our communities.

Is there an easy way of finding out what db tables are changed for each module?
I'm asking because I'm trying to figure out how to deploy and maintain my website. The live version is a community website, so users will be adding content. On the development side, I'll be making changes. I need to figure out if there's a way to only deploy the setting changes to the live version, so I don't clobber data the users have added. I'd rather not put the live site into maintenance mode as I fiddle with changes, and I certainly would like to avoid making changes to the live site while its live.
