Answer / v.sivakumar

In the universe level there is a concept named derived
tables.

We can create a derived table with our own query comparing
2 or more tables as per our requirement and we can generate
reports using the object from that derivesd tables.

In universe level , derived table is consider as View.

Answer / mark

No.

BusinessObjects has the concept of derived tables though.
These are created and held at the universe level. The main
problem is that they are designed by the universe designer
and if this is a different person to the DBA, they will
often get missed in impact analysis when changing database
tables. Similarly they won't perform as well as a solution
based at the database level.

Is there any other repository domains rather than universe, security, document?
