I have tried to convey the same message in several SUGI presentations and
other rantings. SAS makes it easy to check for primary key duplicates,
failures of one-way and two-way referential integrity constraints, and other
anomalies in data. If resolved, series of joins become neatly transitive
and much of programming reduces to highly predictable set-logic operations.
If left unresolved, the accuracy and consistency of results depend on the
current state of the data. Sig
