Power BI is a powerful business intelligence (BI) tool developed by Microsoft. It allows users to connect to various data sources, transform and model the data, and create interactive reports and dashboards. As a BI tool, Power BI is designed to help businesses make data-driven decisions by providing insights into their data in a visually appealing and easy-to-understand manner.

Here are some key features and functionalities of Power BI:
