Need help w/ a trigger

What I want to do is basically maintain a version number for a table. If the table is changed in any way, I want the version number to be incremented.

The best way I can think of is to first have a sequence to generate the sequential numbers. Unfortunately, I guess I would have to store the "version number" in another table with that being the only row and column.

If this is the case, I would need to setup a trigger so that, upon any change to the table, it would increment that version number.

I could use help on the theory (is it the best way to do it?) and also writing the trigger (as I never have before).
