Managing relationships in Power BI

The previous version of Power BI did not correctly recognize pre-existing relationships in the tables when data was accessed from ODATA Service. The recent August 20 update works much better and was able to recognize relationships without a hitch.

This post is about accessing data from ODATA Service feed.

If you are not already having Power BI, you can access the same (review this file).

Launch Power BI and do not use the start screen. However, if you want to read about it, you can go on to the online resources. The following page will be open when you launch this application from its shortcut.

Click on Get Data to open the following:

From the drop-down list pick ODATA Feed and the following is opened. Enter the ODATA feed URL. This is a reference library feed from Odata.org and gives access to Northwind database as an OData Service.

Click OK. The Navigator appears on the left pane and the selected items are shown on the right pane taken one at a time. Presently nothing is selected.

You can chose one table or any number of tables from the tables in the left pane. When you select a table the data in the tables is displayed in the right pane as shown. My last item selected was the Products table and you see the data in the right pane. I have selected three tables for which I know beforehand that relationship between tables exists. Of course you can create relationships as well.

After selecting the tables click on Load and the tables are loaded as queries to the interface and you will see this transient screen providing some loading details.

After loading is complete, the screen changes to this. The tables appear as Fields in the Power BI's UI as shown.

Click on Manage Relationships in the main menu, the following page is displayed. The program has correctly recognized the existing relationships and marks them as active. These relationships can be managed by using the set of buttons in the above page, New | Autodetect..|Edit|Delete.

 Odata_08.PNG

Since it has already detected the existing relationships there is nothing to be discovered should you click Autodetect... as shown here.

You can see how they are related graphically as seen here. Placing your cursor on the line joining the tables in the middle, displays how they are related.

Regarding my book on SQL Azure

I hope my latest book "Microsoft SQL Azure Enterprise Application Development" which should be available in a couple of days appeals to the readers as much as my two other books on Microsoft BI. This book covers most of the changes that took place between the CTP and the updates in October 2010. Even as I am writing this post it must be undergoing more changes, a fact that may take away the shine from what is written in the past. Notwithstanding, the core ideas do not change; what changes perhaps are, a few more modified screens; a new UI; and some additional hooks. The more profound changes will be totally new elements that gets added to product with time and that is the time for yet another book.
