Introduction to the "Family" In the first lesson of the Member
Functions segment of our series, we will take some time to "get
to know the family." I like to call one specific subset of the
member functions and operators the "family" functions, because
many of their names resemble those of family members. The
functions that compose this group include: metaphor is
appropriate, because these functions perform operations on
dimensions, hierarchies, and levels in a manner that mirrors
movement about a "family tree." There are other "family"
functions that return sets, but we will focus primarily on the
member functions in this segment of the will discuss some of the
concepts that underlie the "family" functions, and discuss the
appropriate syntax involved in using each effectively. Next, we
will provide hands-on exposure to the use of each in simple
expressions / queries that we will subsequently run to view the
output and reinforce our understanding of the function /
component from the perspective of the result
