Module 1: Multidimensional Review

• Understand and use multidimensional terminology.
• Define multidimensional terms: Database, Cube, Dimension, Hierarchy, Level, Member.
• Explain the use of Parent Child dimension and Unary Operators.
• Understand the sample database used in the examples and exercises.
• Explain the difference betweeen a “derived measure” (a SQL expression) and a “calculated member” (an MDX).
