What is Microsoft Power BI?

Power BI (or Power Business Intelligence) is a data visualization and business intelligence platform created by Microsoft. Its main purpose is to help users gather, analyze, and visualize data to see the results of the marketing activities and make decisions about the next steps.

With the help of this tool, you can upload raw data from various sources, such as CSV files, spreadsheets, databases, cloud services, and apps, and then transform it to create interactive reports and dashboards. These reports show data in an easy-to-understand way, helping companies deal with complex information.

What are the main goals of Power BI?

  • See and understand data.
  • Create visual reports.
  • Collaborate for decisions.
  • Access data from anywhere.

Power BI history

It started as a set of add-ons for Microsoft Excel known as Power Query, Power Pivot, and Power View. These tools allowed users to connect to different data sources, clean up data, and create interactive visuals. While they were popular, they had limitations because they needed the desktop Excel software.

In 2013, things changed with the introduction of a cloud-based version of Power BI. Now, only with access to a browser, people could create and share reports and dashboards. 

In 2015, Microsoft made a big update, introducing the Power BI Desktop software for more advanced modeling and visualization. They also launched a mobile app so people could view and interact with data on phones.

Since then, Power BI has kept growing. In 2016, they added Power BI Embedded for developers, and in 2017, introduced Power BI Report Server. In 2019, the Premium version arrived with even more features and capabilities.

Since then, it has become a must-have tool for businesses worldwide, used in many industries like banking, retail, insurance, oil and gas, and manufacturing.

Tool #5. Power BI mobile app allows you to access and interact with reports and dashboards on your mobile devices, ensuring that data insights are available on the go. It works offline, so you can view reports even without an internet connection.

Power BI architecture

The main component of Power BI is its data modeling engine, which organizes and optimizes data to ensure efficient analysis.

Once your data is prepared, you can upload it to Power BI Service, a cloud-based platform. Here, you can collaborate on reports and dashboards with your team. It also provides the Power BI gateway for integrating on-premises data sources securely. 

Let’s take a look at the key components:

Power BI features

Visualization

4.visualization

Power BI offers a wide range of visualization types, from simple number displays to complex gradient-colored maps.

Datasets

5.datasets

Datasets are the raw materials for creating your data insights. They are basically collections of numbers used to make visualizations. A dataset can be as straightforward as a single table from an Excel spreadsheet or a blend of data from various sources, offering a unique cluster of information. Filtering data within datasets allows you to focus on specific information relevant to your analysis.

Reports

6.power bi reports

A report is a collection of visualizations that present data. They can spread across several pages. You can create different visual elements, arrange multiple pages, and structure them to better communicate your message. Whether you’re analyzing quarterly sales, monitoring product growth, or examining wildlife migration patterns, reports help you gather and showcase your data insights in a clear and shareable manner.

Dashboards

Dashboards serve as the front door to your reports and visualizations. They consist of selected visuals that offer immediate insights, are limited to a single page, and provide end users with an interactive gateway to explore underlying reports. For more details, see our article on Power BI dashboard examples.

Tiles

7.power bi tiles

Tiles are individual visuals within a dashboard, which contain specific visualizations and can be moved, resized, or arranged to create a connected and informative dashboard. While users can interact with tiles when using shared dashboards, they cannot change their layout or size.

How does Power BI work?

It connects to data sources, then extracts and transforms the data, and finally creates reports and dashboards. Users can then publish these reports to Power BI Service for sharing and collaboration. Let’s take a look at the process in more detail:

1. Data integration. You can connect to different sources, including databases (SQL Server, Oracle, etc.), cloud services (Azure, AWS), spreadsheets, and web services. 

2. Data transformation. After connecting to data sources, the Power Query component will extract and transform numbers. It can delete duplicates, standardize, and combine data from different places, making it pretty for analysis.

Example: 

Suppose you have a dataset with different date formats (e.g., “01/15/2023” and “15-Jan-23”). Power Query can be used to standardize these formats into a consistent one, making it easier to work with.

8.data transformation

3. Data modeling engine allows users to create relationships between different tables, define hierarchies, and calculate new measures using Data Analysis Expressions (DAX). This step creates a structured data model for analysis.

4. Report creation. After that, you can generate reports and dashboards in Power BI Desktop, selecting from various charts (i.e. column chart, bar chart), tables, and maps.  

5. Publishing. Once reports and dashboards are ready, you can publish them to Power BI Service, Microsoft’s cloud-based platform for sharing with team members. 

6. Data refresh. It supports scheduled data refreshes, guaranteeing that reports always display up-to-date information. It automatically updates the data from the original sources based on defined schedules.

7. Sharing and collaboration. Reports and dashboards can be securely shared with colleagues or stakeholders through Power BI Service. At the same time, as an owner, you can control access to the content through role-based permissions.

8. Mobile access. Mobile apps for iOS and Android devices give access to reports and dashboards on smartphones and tablets. They are optimized for smaller screens and offer offline access.

9. Integration and embedding. For more advanced KPIs, developers can use Power BI Embedded to integrate reports and dashboards into custom applications or websites.

Power BI data connections

Power BI Desktop provides built-in data connections to access different data sources such as Excel files, databases, cloud services, and more. However, users can explore alternative methods to link their data sources. These methods include using IPaaS (Integration Platform as a Service) solutions like Coupler.io, ODBC (Open Database Connectivity) drivers, and other data integration approaches.

It’s quick and user-friendly, taking just a couple of minutes to connect data from 50+ sources like GA4, Facebook Ads, Mailchimp, and others without requiring coding or complex setups.

To establish the connection between GA4 and Power BI, you’ll need to create a Coupler.io account, which can be done using your Microsoft account. Then, simply add a new importer, select the source and destination (Power BI), and you’re ready to go.

Step 3: How to clean data with Power Query Editor

  • To begin transforming your data, find the Power Query Editor by clicking on the “Transform Data” option located in the Home tab of Power BI Desktop.
13.power query editor

When you’re working in Power Query Editor, every action you take to shape your data gets recorded as a step. These steps are automatically applied each time the query connects to the data source, ensuring your data remains consistently formatted according to your specifications. 

  • Identify column headers and names and make sure these headers are correctly placed.
14.identify column headers and names
  • Promote headers. Sometimes, the first row of data might contain column names, and Power BI doesn’t recognize it. You can fix this by promoting the first row as column headers using the “Use First Row as Headers” option in the Home tab.
15.promote headers
  • Review your column headers and ensure they are clear and descriptive. You can rename them by right-clicking and selecting “Rename” or double-clicking and typing the correct name.
  • Remove unnecessary rows and columns. If you have blank or irrelevant rows at the top of your data, you can remove them. Use the “Remove Rows” option in the Home tab to clean up your data.
