Microsoft Power BI For Dummies Cheat Sheet

Cheat Sheet / Updated 03-01-2022

Microsoft Power BI is an enterprise-class data analytics and business intelligence platform that users connect to for data analysis, visualization, collaboration, and distribution. The platform takes a unified, scalable approach to business intelligence that enables users to gain deeper data insights while using virtually any data source available. With Power BI, you can access tools to support the entire data analysis lifecycle — from importing to transformation to visualization and collaboration. Power BI, as part of the Microsoft Power Platform, is complementary to its sister application of Power Apps (for no-code/low-code application development), Power Automate (for workflow development), and Power Virtual Agents (for chatbots.). Each of these applications works well with one another. Strong integration opportunities also exist between Microsoft 365 (Word, Excel, PowerPoint, and SharePoint) and Dynamics 365. When you’re looking to realize the value of your data using Microsoft applications, or even third-party applications, Power BI can provide the insights you and your organization look for at speed and scale.
