Teradata has a Join Index which is what I think you're looking for.

In addition, a Join Index is always maintained by the DBMS (I'm sure that with Oracle you have to issue an "update my materialised view" command) and there's no log file required.

Downsides are that you can't Multiload a table which has a JI defined to it. You'd need to DROP and reCREATE the JI.

Cheers,

Dave
