About this course

Tech type Performance Plus
Course code QAMDX
Duration 3 Days

This course starts with a grounding in the OLAP terminology and architecture that underpins the use of MDX. The fundamentals of writing MDX code are covered, followed by an introduction to the functions and constructs that are of immediate benefit to new users. The examples used all have relevance to business applications.


  • It is assumed that delegates attending this course will already have had some exposure to Data Warehousing and OLAP.

  • Programming experience would also be very beneficial, but is not essential.

Delegates will learn how to

At the end of this course you will be able to:

  • appreciate the power and flexibility of MDX for solving real business problems by releasing knowledge from an OLAP cube
  • understand the syntax of MDX and its most common constructs
  • navigate the hierarchy of a cube
  • use the most common MDX functions and know how to access further functions
  • write MDX stand-alone queries for interrogating an OLAP cube
  • write MDX expressions (versatile code segments) for a wide variety of purposes
  • create new calculated measures within a cube



  • What is MDX; MDX's origins and likely future

OLAP terminology and cube architecture

  • Dimensions, measures, members and cells; hierarchies and aggregations; levels; tuples and sets; member properties

MDX syntax

  • Brackets, square brackets, curly brackets; dots and commas

MDX queries

  • Using MDX for querying; SELECT, FROM, ON COLUMNS, ON ROWS, WHERE

MDX expressions

  • The current cell; relative cell referencing; comparing values, comparing values between years, calculating values to date

Navigating the hierarchy

  • Functions for navigating a hierarchy: Children, Parent, Descendants, Ancestor, Siblings, Cousin; nesting functions

Moving averages

  • The type of problem solved with moving averages; a simple example; a more complex example that behaves intelligently within a hierarchy

Parent-child dimensions

  • Overview of parent-child dimensions; why they are useful and how they are implemented

More advanced querying
