A well-behaved one would pretty much have to. Changing the logic that is supposedly bound to my data would, in general, change the meaning of my data. The DBMS has no business doing that without my say-so.

I was once compelled to work with an OODBMS--admittedly an astonishing dog of a thing, and therefore perhaps not a fair example--but it certainly made no attempt to (logically) save the methods for each instance. And it was unusable just for that reason alone. (There were of course many others besides.)
