Introduction
This course provides students with the knowledge and skills necessary to use multidimensional expressions (MDX) to add calculated members and other dynamically calculated values to a Microsoft SQL Server™ 2000 Analysis Services cube by using SQL Server 2000.
At Course Completion
After completing this course, students will be able to:
- Understand and use multidimensional terminology.
- Add calculated members to a cube.
- Use MDX member functions to navigate within a hierarchy.
- Use MDX time functions to compare values over time.
- Use MDX set functions in a query statement.
- Use functions to manipulate sets of members.
- Use functions to aggregate values from a set of members.
- Apply MDX to make a cube change dynamically.
- Calculate formulas for specific blocks of cells.
- Control the order of calculations within a cube.
- Apply MDX in common customer and sales applications.
- Apply MDX in common financial applications.

At the end of this module, you will be able to apply tuples for retrieving values from a cube and creating practical calculations.
This includes:
- Understanding basic concepts of multidimensional coordinates, including how to retrieve values from a cube by specifying a member from a single dimension.
- Defining a tuple and using tuple expressions to retrieve values with two or more dimensions.
- Using tuple expressions to retrieve values for calculating percentages of a total.
- Using tuple expressions to retrieve values for period-to-period growth percentages.
- Creating Simple MDX Queries
The following topics are covered in this module:
- Understanding MDX Query Statements
