How to create an record log/history?

[sfgiantsjo]

I need to create a "History" of jobs held by employees - what's the best tool to use? Bsically I need it to serve as an Audit Log as well as a visible "employment record". Does that make sense? I really have no clue as to where to start. Tips? Too general of a question?

Thanks in advance!
