# Stairway to MDX - Level 5: Members, and an Introduction to the MDX Members Functions

Bill explains what is meant by a 'Member' and 'Member function' in MDX. A member is an item in a dimension that include the 'measures' which are the values of the attributes that belong to a dimension. 'Measures' are themselves members of a dimension called the “measures” dimension. MDX has a set of functions, known as member functions, each of which allow us to perform operations upon any member of a dimension
