Power BI Tutorial

This MS Power BI Tutorial helps you learn this tool from basic to advanced. The Power BI links below will show you the step-by-step approach to connecting with multiple data sources, data transformations, and creating reports like charts, tables, matrices, maps, etc., with screenshots. Use them to learn all the important concepts of the Microsoft Power BI tutorial step by step.

What is Power BI?

Microsoft Power BI is one of the most popular Data Visualization tools and a Business Intelligence Tool, and this tutorial explains everything about it. 

Power BI is a collection of connectors, apps, and software services that work together for business users to convert large junk data into more meaningful insights. Typically, an Organization gets its data from Text, CSV files, Excel spreadsheets, databases, data warehouses, or the cloud. 

Microsoft Power BI lets you connect with all kinds of data sources to get your data. Transform data, model data, visualize (charts), and share them with anyone.

Microsoft Power BI is a cloud-based data analysis and analytics or reporting technology. It incorporates several powerful components, each having its own role in creating reports. For instance, connecting to data sources, data cleansing, analytics, calculations, sharing reports, consuming, etc.

It also allows data analysts to publish reports for your organization. So that business users can access them using mobiles, tablets, etc. This Microsoft Power BI tutorial also explains these steps, so read this thoroughly to learn everything about this business intelligence tool.

Power BI Architecture

It has a user-friendly environment, and it is straightforward to create reports. We can divide Power BI architecture into three elements, and this tutorial further divides it into three more.

  • Desktop
  • Service
  • Mobile App
  • DAX
  • Reporting Server
  • Report Builder

Power BI DAX and Modeling

DAX stands for Daa Analysis Expression Language. It is a powerful language, and you have to use it to write calculations. In Desktop, the Modeling tab is one of the powerful ones because here, you can create a new Table, Column, Parameter, and Measures. You can also manage and view Roles and the relationships between tables. To create a Measure or any calculated field, you must use DAX.

Power BI Tutorial on Calculated Fields

This section covers the calculated fields. Sometimes, we don’t get the columns that we need to perform visualization. In these situations, we can create calculated fields that we have shown below. Then, we can write simple arithmetic operations within these columns or the most powerful DAX functions.

  1. Calculated Columns
  2. Conditional Columns
  3. Calculated Measures
  4. Calculated Tables
  5. Custom Columns

MS Power BI DAX Tutorial

Power BI Desktop

When someone is talking about Power BI, it’s about the Desktop only. It is a lightweight and absolutely free tool that you can download, install and use on the local machine.

The installation process consists mainly Next button, and we covered it along with screenshots. So please refer to Download and install Desktop to follow this tutorial or create our reports.

It is a window-based desktop application helpful for connecting with data sources, transforming, preparing reports, and publishing them to service.

The most common use of the Power BI Desktop includes

  • Connect with many data sources, such as text files, databases, excel files, etc., to import data.
  • Data transformation, cleanups, or combining data from multiple data sources and assigning relationships are often called modeling.
  • Create a report that combines one or more pages, and each page has its own chart.
  • Design graphs, charts, and maps to illustrate the imported data visually.
  • Publish reports to Services or Reporting Server.
  • Finally, we can share those reports across the organization.

Power BI Desktop Interface

  1. Menu: It has all the common actions that we perform regularly. The Home tab has the option to connect with any data (Get Data), recent sources, visuals, publish to a server, etc.
  2. Report Navigation: Here, you can navigate between the report, underlying data in the data set, and the relationship between the tables. Use those three tabs to view or alter the data and their relationships.
  3. Report Designer Area: You drop or add charts or visuals to design and develop Power BI reports here. Check the below section.
  4. Page Navigation: It is Tab based on navigation where you can shift from one report to another by selecting them. Remember, a report might have one or more pages, and each page has it’s own visual or chart.
  5. Fields Pane: This is where you see all the columns available to design reports. It displays all the fields or columns from the chosen data set to work. You have to use these fields in the visual configuration pane for designing a chart.
  6. Visualizations: It shows a tiny icon of all the available visuals or charts. Clicking those icons will generate that visual on the report designer. Microsoft also allows you to add your own chart or visual to this list.
  7. Visual configuration pane: After choosing the required chart from the Visualizations pane, you must configure it. This pane is all about adding fields such as the X-axis and Y-Axis values. Apart from this, it has the formatting options such as changing colors, adding a legend, adding tooltips, etc.
  8. Filters Pane: If you want to apply some filters on the page data or chart, then you have to use this pane. The desktop support filters range from page to report level, and we covered all of them in the filter sections.

Power Query

The Power Query combines connecting to different data sources, getting data or tables from those, transforming them as per the requirements, and loading them into the dataset. The first two steps connecting and getting tables, can be done by the “Get Data” option in the Home tab. Then, when you click on the “Edit Queries” option, you have the chance to transform tables as per your need. And it is a place where you have to apply all data transformations because it happens before data loads into Power BI.

Some of the everyday things that we do in this Power BI tutorial step include: changing data type, combining data from multiple data sources, adding a new column, removing an existing column, etc.

The Power Query user interface

  1. Transformation Options: The Menu has different tabs, and by default, it opens with the Home tab with frequently used items. And each tab has other options for performing data transformations.
  2. Formula Pane: It is the place where you have to write a BI DAX query to transform data or data modeling. Or edit or alter the existing formula to clean the data.
  3. Data Preview: It displays the data (rows and columns) inside the selected table. It doesn’t display all the records, but it shows a preview to get an idea of its data.
  4. Queries Pane: List of all the tables available in a dataset. It divides the columns into dimensions, measures, and other queries (for unknown tables).
  5. Query Settings Pane: It has two options: you can change the properties of the selected column or undo/redo the applied steps to it. Because it keeps a record of each step you have taken in data transformation. So, while applying the transformation, if you have made any mistakes or want to change something, you can use this pane to remove those steps at any point.

Work Flow

  • The Power BI workflow tutorial typically begins with opening the Desktop and connecting to the data source.
  • Data cleanup or transformation is an optional step.
  • Building reports
  • Publish them to Service and share them with other users.
  • Access worksheets, reports, and dashboards from Mobile devices, interact with them, and comment about them.

Power BI Service or Online

The Desktop, Power Query (Get Data), Transformation, and DAX components are useful for loading data, transforming it, and visualizing them in a meaningful chart. However, you need a service to deploy them so others can access them.

Although you can design reports using a Power BI desktop application, you need an online SaaS (Software as a Service) service to share your work across the organization.

To work with the service, you need an account and a Pro service subscription as well. Microsoft allows you to create a free account and provides 60 days trial period. It might be helpful for users who want to learn or explore things.

It is where you publish your reports and dashboards and share them with your organization or others. Here, you can configure the subscription users, roles, Security, etc. We covered everything from registration to free trial to share reports in the Dashboard section.

The exciting feature is that you can create a report or dashboard right from the service itself using online data. 

Power BI Mobile App

Microsoft provides a Power BI mobile app for Windows, Android, and IOS devices. It is a free app that users can install to consume business insights.

After you log in to the account, you can see all the workspaces shared. The best part is that you have an option to add annotations and share them with colleagues. For instance, if you see a sudden hike in production wastage or a drop in sales, you can simply point it out and share. By this, other can understand your concerns and explains accordingly.

Power BI Report Server

When you publish a report to the Service, it will store in the cloud server. However, it is not viable for organizations because they always prefer to keep their data and reports within the premises.

Microsoft has a Power BI Report Server and works like SSRS tutorial (SQL Server Reporting Services Report Manager) to support this. Compared to Services, there are some limitations with Report Server, but you have complete control.

Report Builder

It is a tool you can download from the Microsoft website to create paginated reports and publish them to Service.

Power BI Vs. Query Vs. Pivot

The Power Pivot is also called DAX, and it is the brain/heart or whatever you call it. The entire application depends on it because it turns data into information.

Power Query is the actual data that you want to transform and visualize. By using the Pivot, we can get data from different data sources. However, there are some situations (in fact, all the time) where we must perform cleanups and data transformations. In these situations, we have to use the Query to shape data.

Pivot is all about calculations and shows the calculated metrics, which might not be helpful from the business perspective. To create a chart or any visual, you need Power BI.

Power BI Roles in an Organization

  • You might use APIs to push data into datasets if you are a developer. Or you may use or embed the visual into your application.
  • Some people work on Desktop or Report Builder to design and publish the reports to Service.
  • If you are in a decision-making position, you might use the Mobile App to view Analytics to find what went right and wrong.
  • Few members from Administration work on Services to grand and revoke permissions to users and design light-weighted reports within the workspace.

Is Power BI difficult to learn?

I don’t think so. It is very easy to understand, even for beginners. It is another interface with all the features if you are from the MSBI background or any BI tool.

The DAX part of the functions might be difficult to understand. However, practicing them will give the experience.

Can I learn Power BI on my own?

Yes. Following this tutorial or Microsoft’s own material will help you learn on your own. In this Power Bi tutorial, we started with the basics to more advanced features that might help you crack interviews.
