Glenn,

Be careful with this often-quoted truism - an Oracle schema is NOT the same
as a database in Sybase, Informix, SQL Server or DB2.  (For those who have
heard my rant on this before, now is the time to groan and hit the Delete
button).

A schema is a schema ... the same concept exists in all of the DBs mentioned
above.

Apart from the problems already highlighted (no independent tuning, no
independent upgrades/patches to Oracle, no fine control on some privileges
(resource, dba, etc.)), there are also backup and restore problems.  If
sub-section A calls to say "Quick!, it's gone down the tubes, restore last
night's backup", think of the complication you'll face when sub-section B
says "no way".  It can be done, but involves a lot more efforts (e.g.
restoring to another instance, exporting the schema, then importing it -
instead of just a normal restore).

If that doesn't put you off (and it doesn't have to), then try it out.  Just
don't refer to it as being like a database in informix of sybase :-) :-) :-)

Ciao
Fuzzy
