什么是权力BI？

In Simple terms Power BI is a Business Intelligence (BI) Software. As per Microsoft definition “Power BI is a collection of software services, apps, and connectors that work together to turn unrelated sources of data into coherent, visually immersive, and interactive insights. Your data may 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.”

The parts of Power BI

Power BI consists of many elements that are together, starting with these three basics elements:

• A Windows desktop based application called Power BI Desktop.
• A Web SaaS (Software as a Service) service called the Power BI service.
• Power BI mobile apps for Windows, iOS, and Android devices.

These 3 elements—Power BI Desktop, the Power BI service, and the Power BI 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.
