A friend sent me the query below about versioning the data in a database. I thought I'd throw it out to the list and ask what, if any, versioning solutions you see being used.

Jonathan,
Can you recommend a book that explains different strategies for implementing data versioning in relational databases? I'm no database expert. My intuition tells me that for each table, I'd want to start by adding an extra column containing a revision number. So each change to the data results in a new row with a new revision.
This seems inefficient, particularly when you have 30 columns and only two fields changed...it results in a lot of redundantly stored data.
I guess I'm just not searching for the right thing, because I cannot find any good info on this topic. I'm mostly interested in "generic" relational/SQL solutions that would work on a variety of databases,
