Stairway to MDX - Level 3: The Order() Function
The Order() function provides the 'hierarchized' sorts you need for reports and applications using MDX. In this Step, Business Intelligence Architect Bill Pearson explores using the versatile Order() function for providing dataset sorts that respect dimensional hierarchies.
Stairway to MDX - Level 4: The Order() Function: Beyond Cube Hierarchies
Bill Pearson continues his examination of the versatile Order() function, focusing upon its use in providing dataset sorts that reach beyond dimensional hierarchies
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.
