The answer to the exercise will be included and explained if you attend the course listed below!
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
If you haven't already done so, run the SQL script in the above folder in SQL Server Management Studio to generate a database (not for commercial use or copying) called MAM.
Create a new Excel 2013 workbook, and go into PowerPivot.
Import the following tables: tblAnimal, tblCentre, tblPos, tblProduct, tblQuadrant, tblRegion, tblSpecies, tblStore, tblTown, tblTransaction, and use this data model to create the following pivot table:
The total quantity of sales by quadrant and species.
You can just drag the Quantity column into the Values section of the pivot table field list to create an implicit calculated field (ie a measure!).
Now use the PowerPivot ribbon in Excel to create two new measures (aka calculated fields):
Creating a calculated field in Excel.
The measures are:
|Measure||What it calculates|
|Cheap||Total quantity sold for goods where the price is less than £10.|
|Expensive||Total quantity sold for goods where the price is £10 or more.|
Add these measures to your pivot table:
The pivot table showing one implicit measure and two explicit ones (sorry, "calculated fields").
Save this workbook as Baby sibling, then close it down.
Create a new SSAS tabular model project, importing this PowerPivot model, and have a look at the tables, relationships and measures created to check that everything has come through OK.
Analyse this model in Excel to create - we hope - the same pivot table:
Something has gone wrong if the figures aren't exactly the same.
Take a moment to reflect on whether prototyping like this in PowerPivot is right for you!
