The company was set up in 1967, presumably ...
If yoiu're using Analysis Services 2012 or later, you'll need to analyse your cube in Excel to see a pivot-table-style view of it similar to the one shown above.
Create a new project and data source view, and add in and join the following tables or views:
- dimStaff (this will be our fact table for this exercise)
- dimStore (this will be one of our two dimensions)
Auto-generate a new time table called Time to include the calendar year, starting from 1st January 1940 and running to the present day. Remember to generate the schema! You may now have to wait a minute or so.
Return to your data source view and create relationships between the two staff date columns and your new calendar table's date key column:
You'll also need to create the relationship between the staff and store tables
Create a dimension on the dimStore table, to allow browsing by quadrant.
Now create the cube as shown above, using the number of staff as your measure:
The measure we'll show comes from the staff fact table
You've just created role-playing dimensions:
