Power BI is a business analytics service provided by Microsoft. It provides interactive visualizations with self-service business intelligence capabilities, where end users can create reports and dashboards by themselves, without having to depend on any information technology staff or database administrator.
The initial preview of Power BI was unveiled by Microsoft in September 2014 as Power BI for Office 365. The first release of Power BI was based on the Microsoft Excel–based add-ins: Power Query, Power Pivot and Power View. With time, Microsoft also added many additional features like Question and Answers, enterprise level data connectivity and security options via Power BI Gateways. Power BI was first released to the general public on July 24, 2015.
