Hi,

as I remember, it was always recommended to avoid the use of views upon views upon views in the design of an Oracle DB (as for version 7/8), since the optimizer might get confused.
Does that still apply ?
I'm supposed to give some guidelines to developers about the usage of views.
My point of view is, that views should only be used to grant limited access to tables in a schema (horizontal/vertical) or to consolidate/pre-calculate data.

Any input ?

Regards,
Stefan
