What is POWER BI?


What is Power BI?


Power BI is a business intelligence tool that allows you to connect to various data sources, and is a collection of software services, apps, and connectors that work together to turn your unrelated sources of data into coherent, visually immersive, and interactive insights. Your data might be an Excel spreadsheet, or a collection of cloud-based and on-premises hybrid data warehouses. Power BI lets you easily connect to your data sources, visualize and discover what’s important, and share that with anyone or everyone you want.

Power BI is made up of 3 main elements:


  1. Power BI Desktop — A windows application and free desktop application for building and designing reports.

  2. Power BI Service — An online software as a service (SaaS) for online publishing service for viewing and sharing reports and dashboards.

  3. Power BI mobile apps — It is an app for Windows, iOS, and Android devices for viewing reports and dashboards on the go.


These three elements — Power BI Desktop, the service, and the mobile apps — are designed to let you create, share, and consume business insights in the way that serves you and your role most effectively.

Beyond those three, Power BI also features two other elements:


  • Power BI Report Builder, for creating paginated reports to share in the Power BI service

  • Power BI Report Server, an on-premises report server where you can publish your Power BI reports, after creating them in Power BI Desktop.


Compare Power BI Desktop and the Power BI service:


Power BI Desktop is a free application that you download and install on your local computer. Desktop is a complete data analysis and report creation tool that is used to connect to, transform, visualize, and analyze your data. It includes the Query Editor, in which you can connect to many different sources of data, and combine them (often called modeling) into a data model. Then you design a report based on that data model. Reports can be shared with others directly or by publishing to the Power BI service. Sharing reports requires a Power BI Pro license.


The Power BI service is a cloud-based service, or software as a service (SaaS). It supports report editing and collaboration for teams and organizations. You can connect to data sources in the Power BI service, too, but modeling is limited. The Power BI service is used to do things such as creating dashboards, creating and sharing apps, and analyzing and exploring your data to uncover business insights.
