OLAP Model
9/2/09

6. OLAP Structure
Dimensions
Hierarchies

Members
Attributes

7. OLAP - “Member”

8. Cognos Studios
Report Studio
Analysis Studio
Query Studio
9/2/09

9. Report Studio
Drag & Drop interface with Automatic Expressions
Faster Development time
Automatically generated logic with dragging – such as “sets”
Use DB Functions & SQL, MDX Generation
Advance filtering, Sorting, Calculations
Take adv of dimensional and relational style reporting
Bursting – a delivery method
9/2/09

10. Report Studio – Drop Zone & Formatting
9/2/09

11. Report Studio – MUN
Member Unique Name (MUN)
Referenced in an Expression
Location of member in Multi Dimensional Structure
[Sales (analysis)].[Time dimension].[Time dimension].[Month]
->[all].[2009].[20091].[200901]
9/2/09

12. Report Studio – Sets
Group of Members from a Single Hierarchy
Set(member{,member})
9/2/09

13. Report Studio – Tuple
Measure values at the intersections of members from DIFFERENT
dimensions
Tuple([2006],[Computer Hardware])
9/2/09

14. Report Studio – Current Measure
Member of the hierarchy returned during an iteration
9/2/09

15. Report Studio – Filter
Used as an expression syntax to define data items on column or row
edges
filter(set_exp, boolean_exp)
9/2/09

16. Report Studio – Slicer
Provides context to intersection values
Affects the values of the cells of the report but not the Rows or
Columns
9/2/09

17. Report Studio – Summary Functions
Summary Functions return value calculations based on member sets
Total(<currentMeasure|expr> within set set_expr {, set_expr})
Result based on Expression Argument
Aggregate (<currentMeasure|expr> within set set_expr {, set_expr})
Result based on Rollup rules defined in the Data Source

23. Best Practices in Report Designs
Be wary of OLAP Design including Rollup
aggregations
Appropriate functions for correct values
Build Prompts
Slicers - Often improve performance
Format the report
