RE: Re[2]: What Sort of Privilege?

The many schema method is easy to handle. The schema owner grants
privileges to the dba with admin option
and the dba controls the roles. The schema owner/user can only "see"
the tables that they own or are granted
access to. With many schemas sharing a few "common"  tables from the
majority( size wise) of the database, control and access
is easy. We have 11 in house applications that have thier own schemas
and 1 large warehouse type application on the database.
No problems keeping everyone seperated.

Tom,

        Sorry, but you are wrong.  I prefer the many schema method as
well.

Jo,

Well,  The Oracle Apps applications have many schema's - much like what
=
you
described.
I'm guessing that the majority of home-grown applications have only
one
schema for all of the tables.  I could be wrong.  In my view, it is =
easier
to manage.  Everything is in one place.  It prevents you from creating
=
two
database objects with the same name.  Managing security is easier - =
again,
you can issue all your grants from one schema, rather than needing to
=
keep
re-logging in.

Maybe it's just me!

Hi Tom,

we (well, it was in place before I got here, but anyway) basically
have=20
one schema per application. We also have one schema which houses =
"common"=20
data, i.e. data used in many different places/apps; e.g. employees,=20
customers, products, plants, .... So we have many cross-schema FKs to
=
the=20
"common" data but outside that everything is pretty well
partitioned.=20
Maybe that's why I've never really had any problems with it.

Is having what is basically a one-schema database common practice ?

mvg/regards

Jo
