Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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 DAX query in Management Studio (or DAX Studio, if you can get it to work) which lists out for each shopping centre the ratio of square metre area to number of units, with the highest ratio coming first:

Shopping centres

The first few shopping centres - notice the Infiinity for Market Quay.

Use ADDCOLUMNS to add an additional column to the output from the EVALUATE query.

At the start of your query, create an ad hoc measure in the Centre table to calculate the total value of transactions (defined as price times quantity for each), and display this alongside the existing columns:

Additional column

The additional column generated giving the value of transactions for each centre.

Save this query as Yeah, and close it down.
