First, you need to understand the difference between a real database
and a bunch of stuff in a spreadsheet.
Second, you need to think about the value of a couple data sets
'connected' together in some well-defined way. In database
management, we take tables and link them together via keys.
This (eventually) yields a whole slew of data tables, all linked together
through a database schema. A full-scale RDBMS will do this, providing
a view into the entire warehouse of tables.
SAS can do some of this. You can certainly define views and/or
new data sets which are the resultants of linking a collection of
data sets together.
But SAS does more in some situations. If some of your sheets
are just look-up tables, then SAS would use formats to provide
this sort of data translation. It's just a different paradigm.
So what exactly are you looking for? If you explain it in more detail,
someone can undoubtedly tell you how to get there. Unless you're
looking for a way to take a wad of crud that violates all database
standards, and magically cram it into a functional database schema.
