Database tables / fields you always use in your killer apps

I'm hoping to tap into some collective experience here, so What (if any) utility tables, or common fields do you always include in your database design?

What is the best test-as-you-type online regex testing app?

I found a great web app for testing regexes as-you-type, but have lost it in the months since I last use it.

What is the best way to protect user inputs (not yet submitted) from session timeout?

I develop and maintain small intranet web apps(JSP and Resin). Some users takes so much time to complete the forms that, when they submit, they lose all their input data because of session timeout.

MVP - Should the Presenter use Session?

I am using the Model-View-Presenter pattern for a web page. Should the presenter be aware of Session or should only the view be aware of it? I guess what I am getting at is that concepts like Session are very related to the architecture of the view so should they be limited to use by the view? Otherwise what would happen if I wanted to ...
