It depends on context. In the mainframe world, a "dataset" is either a
file ("sequential dataset") or a collection of subfiles within one file
("partitioned dataset"). In the Microsoft world, which is probably what
you're asking about, "dataset" means a collection of one or more tables,
AND any relationships between them, AND any internal working tables that
the database uses to keep everything straight. In the computer science
world at large, "dataset" just means "a bunch of data"!
