It frankly sounds pretty silly to me. Your friend can set up resource
profiles on Database A to limit resource consumption by "bad
queries"...or the developers could be taught how to write efficient SQL!
Also, "bad queries" can be written against views as well, and placing
the views on another database does nothing to make them less bad. Using
db links complicates administration, availability, and performance
optimization.
Tom Kyte (asktom.oracle.com) would have a field day with this one.

Subject: two instance -- one database
I have a friend (no really, this isn't some lame way of telling you about me but trying to hide that by ... )
I have a friend, and at his company they have an Oracle database with tables and data. We'll call it Database A and they have another Database B that has views across dblinks to each of the tables in Database A. The data team says that this protects Database A from bad queries.
So can anyone think of any possible benefit from this arrangement? Will administration be easier, queries faster, performance more predictable? Anything?
