Need Tool For Managing Database Object Ownership

we have a group of developers which have created and asked us (DBAs) to
create many objects in the databases including tables / stored
procedures / functions / etc.

since our company is growing, however we have an increasing amount of
objects that have either been abandoned or have several versions.

in an effort to clean of the huge amount of clutter and anytime that
something simple like a stored proc needs to change, it is almost
impossible to predict exactly where we will see negative effects of
this change.

i am looking for a system (preferably without developing our own tool)
that would keep track of history of database objects (in terms of who
created it and what purpose it has) as well as link that to all the
developers/users we might need to notify of any changes to that object.
Also, this should be linked to the application which rely on the
object.

bottom line... every object in the database needs to have at least 1
corresponding contact as well as the applications which us it.

with this information, we can much more easily maintain objects in our
DBs.

thx
