There are several types of databases:
Relational databases don't allow methods, since you can't extend the
type system.
The object-relational databases support methods for custome types.
As far as I know, which isn't probably much further than I could through you, active object-oriented databases support methods, while passive objekt-oriented databases do not.
A definition of a method may be found in the SQL:1999-Standard for OR-DBMSs or the ODMG-Standard for OO-DBMSs. But it's just a guess.
