Technical Solutions Using Oracle and SAS

Considerations

Can I predict/project data/hardware needs to meet short term goals

What questions can I ask of the data What questions should I ask of the data What are the expectations for answers How can I make SAS and Oracle more

efficient

Do Oracle/SASUsers wish to form a SIG ? What sort of forums do the Users want in

future conferences ?
