The ability to work with sets is critical both to retrieving data from an online
analytical processing (OLAP) cube in a multidimensional expression (MDX)
query statement and creating powerful MDX expressions.
In this module, students will be introduced to functions that return sets of
members. Some of the functions retrieve sets from the metadata defined in the
cube’s dimensions. Some of the functions manipulate those sets to create new
sets that meet specific analytical purposes.
