A procedure's signature is its parameters and output. So say I have a procedure that accepts an int parameter and returns a single resultset of a particular form. I can change the contents of the procedure (optimisation) and the front end app won't notice if I keep the procedure's signature the same, so it must still accept that int and return the same resultset
Make a bit more sense? (no, I don't really understand what its asking either)
