Power BI is a business intelligence service that allows users to turn streams of data into easy-to-digest, visual insights. The data can come in the form of a spreadsheet or another local database. Furthermore, the tool allows you to visualize and understand data that would be otherwise incoherent.
This is especially useful for business executives that need to be able to make decisions at a glance.
Power BI has a desktop application, an online service, and a mobile application – each of which communicates with each other and makes business intelligence insights easy to share. To anyone familiar with Microsoft products, the interface should feel quite intuitive.
