19. Why a cube?
 Performance
 Relational databases not suited for instantaneous analysis
 Cube precalculates (aggregates) data
 KPI and trending

20. Adventure Works example
 A cube is an
 “aggregation of measures
against dimensions”

21. What is a Cube - Example

22. What is a Cube - Example

23. What is a Cube in SQL 2005/2008
1. Data Source
 Where the data comes from
• Adventure works connection string
2. Data Source View
 The tables and how they link together
• Orders, Details, Products and relationships
• Name matching to detect relationships
3. Dimensions
 How we break up the aggregate data
• Products, Time
4. Measures (Facts)
 The aggregate data
• Line Total, Quantity

24. Steps in Creating a Cube
1. Define Data Source
2. Create Data Source View
3. Define Dimensions
4. Define Measures (Facts)
5. Process the Cube

25. Data Source - Database

26. Data Source - Impersonation (Authentication)

27. Data Source View – Data Source

28. Data Source View – Connect Tables (Name
Matching)

29. Data Source View – Select Tables and Views

30. Data Source View
 Manually adjust relationships missed by the wizard

31. Build a Cube – Build Method

33. Build a Cube – Select Measures

34. Build a Cube – Select Dimension

35. Build a Cube - Select Time Periods

36. Build a Cube – Process Cube

37. Build a Cube – Process Cube

38. Build a Cube
 Review Auto Generated Cube
 Check Hierarchies e.g. Product Category shows ID rather than
name

39. Build a Cube – Fix Dimensions

40. Cube Issues
 Keeping things Related
 Dimensions should tie in to Fact tables
 Use Primary Keys
 Keeping things Relevant
 Multiple fact tables
 Even more dimensions
 Keeping things Fresh
 Needs to be processed
 Automated SSIS Packages
 Keeping Missing Data
 Fails to process when keys are missing
 Change missing keys to Unknown

41. That's a Cube!
