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

In Management Studio (or in DAX Studio, if you're lucky enough to have this working) write a query to show for each year and quarter the number of transactions:

Number of transactions

The number of transactions is shown by year and quarter, in chronological order.  There are a couple of modifications you'll need to make to the basic summarisation query to get this to work: filtering to include only calendar rows from on or after 2013, and ordering the final data by year and quarter.

Save this query as More suspiciously unrandom data.txt, then close it down.
