Learning Microsoft Power BI Lesson 3 – Exploring Power BI Desktop

The post “Learning Microsoft Power BI Lesson 3” takes you through the overview and creating the first report using Power BI desktop. Here we have seen how to install the Power BI Desktop on Windows. Now we’ll open it and explore the features:

Power BI Desktop:

Power BI Desktop has 6 main areas:

  1. Toolbar: It contains a set of tools which are used to get data, develop and publishing the reports
  2. Report View / Canvas: Here we actually give life to data using various visualizations
  3. Ribbon: Showcase the common tasks which are associated with the reports and visualizations
  4. Pages: Allows us to add, remove pages in a report
  5. Visualizations: Where we can add, change visualizations, customize colors or axes, apply filters, drag fields etc.
  6. Fields: Where query elements and filters can be dragged onto the Report view, or dragged to the Filters area of the Visualizations pane

Getting Data into Power BI:

We’ll see how to load data from a source to Power BI Desktop. Power BI is a data centric application thereof we need to focus on providing the clean data as per the business requirement. Currently Power BI supports 70 + data sources and these are categorized into 5 types:

File: Excel, Text, CSV, XML, JSON, Folder, SharePoint Folder

Database: Ex: SQL Server, Oracle, DB2, PostgreSQL, SAP, MySQL, Amazon Redshift, Impala etc.

Azure: Ex: Azure SQL Database, Blog Storage, Azure Table Service etc.

Online Services: Ex: Dynamics 365, Sales Force / Reports, Facebook, GitHub etc.

Other: Ex: R Script, OLEDB, ODBC, Hadoop File, Active Directory etc.

I would suggest download and attach/restore [AdventureWorksDW2014]

Select SQL Server Database and connect it:

Now we have to select tables to import from SQL Server to Power BI. We’ll choose two tables from database [AdventureWorksDW2014]:

[DimProduct]: It stores product properties / metadata that might include name, color, height, weight, stock, price etc.

[FactInternetSales]: It stores product sales information that might include sale amount, tax amount, date info, discount info etc.

 Note: If you are new to dimensions and facts don’t worry about it, just google it and see what is a FACT and Dimension. To simplify fact indicates numbers / measures and Dimension gives a meaning to fact using its properties / metadata. Ex: If I say 5 Cameras it’s just a measure which doesn’t have any meaning now if I say Mr.Chris has purchased 5 EOS cameras from Canada e-store on 14-Sep-17 gives a proper meaning. Here 5 is the FACT and dimensions are Customer (Chris), Product (Camera details), Country (Canada), Store (e-store) and Date.

Import above tables into Power BI:

Just try to go with the flow, we are just exploring the Power BI desktop for the first time and not going to try all the options in one go.

Go back to the Report TAB and now we are going to design a simple report:

Let’s have a look at Visual (Clustered Column Chart) Properties:

We’ll use “Fields” and “Format” tabs and apply few customization:

The chart is showing the Sales Amount based on the “ShippingDate”. It’s automatically groups data based on “Year”, “Quarter”, “Month” and “Day”. We’ll remove Month and Day as we just required Year and Quarter.

Now change the Chart data colors, Format the Chart Title, X-Axis, Y-Axis text size etc. Select the Chart and go to Format tab:
