Why "Data Structures"?

As in other software systems, SAS makes use of purpose-related data structures, being aware of the advantages emerging from appropriately structured data.

Apart from nowadays well known data tables and data views, SAS provides the programmer with a generalized approach on views beyond SQL views as well as ultra-fast read-only structures for left outer joins and, finally, a metadata repository in physical memory (!) with support for hierarchical modular programming.


So, the answer is: "Data structures are the key to flexibility and efficiency in SAS programming!"
