"db" names a lookup table where selectable values can be found, if you're using a selectish widget for the control.  There is another field (lookup?) where a pair of fields in that table can be set to be the value and label for each option.  I think it's often added automatically by the template editor when the control is modified, whether or not it's necessary.

I don't remember it being very useful for anything else, and for text controls it can generally be deleted--especially if the only thing after it is ^@.  In vi, ^@ is a text representation of a null (\0) (end of C string) (perl CGI multi-valued-argument separator).
