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). Once you've done this:
  1. Go into SQL Server Management Studio;
  2. Open the SQL file you've just unzipped (you can press CTRL + O to do this); then
  3. Execute this script.

This will generate the database that you'll need to use in order to do this exercise (note that the database and script are only to be used for exercises published on this website, and may not be reused or distributed in any form without the prior written permission of Wise Owl).

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.

Create a new Power BI Desktop file, and import the following tables:

Tables to import

Import these tables from the Make-a-Mammal database.

 

Create a map to show the number of purchases by family and postcode:

Count of purchases

There are a lot of postcodes, so this looks a bit messy.

 

From a recent source, import the tblTown table also, and change your map so that the town name is the Location field:

Purchases by town

This is not an improvement!

 

Create a calculated column in the town table to localise things a bit:

Towns in the UK

Let's pin those towns down to the UK ...

 

Use this column as your location:

Town location

Still a bit messy. Time to filter a bit?

 

Add a filter to the visualisation to show only South-West data (you can do this by saying that the town's RegionId must equal 7):

South-West purchases

Yeah! Finally, a map that looks sensible.

 

Save this Power BI Desktop file as Cream Teas, then close it down.
