What is Power BI Desktop?

Power BI Desktop is a free application that you can install on your local computer. It allows you to connect to, transform, and visualize your data. With Power BI Desktop, you can:

Connect to multiple different sources of data.

Combine data sources into a data model (often called modeling).

Create visuals, such as charts or graphs, to represent your data.

Create reports that are collections of visuals on one or more report pages.

Share these reports with others within your organization using the Power BI service1.

It’s commonly used by data analysts and business intelligence professionals to create reports and then share them with others. Power BI Desktop is updated monthly, incorporating new features and customer feedback. The most recent version of Power BI Desktop is supported and can be downloaded from the Windows Store or as a single executable containing all supported languages1.

There are three views in Power BI Desktop:

Report view: Where you create reports and visuals.

Data view: Where you see the tables, measures, and other data used in your report’s data model, and transform the data for best use.

Model view: Where you manage the relationships among tables in your data model1.

1. Data Connectivity: Power BI Desktop allows users to connect to a wide range of data sources, including databases (SQL Server, MySQL, Oracle, etc.), files (Excel, CSV, XML), online services (Google Analytics, Salesforce), and more. This versatility enables users to access and analyze data from various sources within a single interface.

2. Data Preparation: With Power BI Desktop's intuitive interface, users can easily clean, transform, and shape their data using a powerful tool called Power Query. This feature allows for data cleaning, merging, splitting, and other transformations to ensure that the data is structured optimally for analysis.

3. Data Modeling: Once the data is imported and prepared, users can create a data model within Power BI Desktop using its Data Model feature. This involves defining relationships between different data tables, creating calculated columns and measures using DAX (Data Analysis Expressions), and optimizing the data model for efficient analysis.

4. Visualization: One of the standout features of Power BI Desktop is its extensive library of visualization options. Users can choose from various chart types, graphs, maps, and custom visuals to represent their data in meaningful and engaging ways. These visualizations can be easily customized and formatted to meet specific reporting needs.

5. Report Creation: Power BI Desktop allows users to design interactive and dynamic reports by combining multiple visualizations onto a single canvas. Users can add slicers, filters, and drill-down capabilities to enhance interactivity and enable deeper insights into the data.

6. Publishing and Sharing: Once reports and dashboards are created, users can publish them to the Power BI Service—a cloud-based platform where they can be shared with colleagues or stakeholders. This enables collaboration and real-time access to insights across the organization.

7. Regular Updates: Microsoft regularly updates Power BI Desktop with new features, enhancements, and bug fixes to improve usability and performance. This ensures that users have access to the latest tools and capabilities for their data analysis needs.

Overall, Power BI Desktop is a versatile and powerful tool for data analysis and visualization, suitable for both individuals and organizations looking to unlock the value of their data. Its user-friendly interface, robust features, and seamless integration with other Microsoft products make it a popular choice among data professionals worldwide.
