The rise of Business Intelligence tools posed a challenge to Microsoft to build its own business intelligence tool. Microsoft introduced Power BI to deliver compelling analytical capabilities to existing Microsoft Excel and upgrade it to be intelligent enough to generate interactive reports.

According to Gartner’s Magic Quadrant, Microsoft Power BI is one of today’s top business intelligence tools, chiefly because most IT firms rely on Power BI for their business analytics. As a result, the current IT industry finds a massive demand for Power BI Experts. 

Tableau is a highly regarded and widely used data visualization and business intelligence (BI) software platform. It’s designed to help individuals and organizations explore, analyze, and visualize data to gain valuable insights and make informed decisions.

What is Power BI?

Power BI is a business analytics tool developed by Microsoft that helps you turn multiple unrelated data sources into valuable and interactive insights. These data may be in the form of an Excel spreadsheet or cloud-based/on-premises hybrid data warehouses. You can easily connect to all your data sources and share the insights with anyone.

Why should we use Power BI?

Power BI provides an easy way for anyone, including non-technical people, to connect, change, and visualize their raw business data from many different sources and turn it into valuable data that makes it easy to make smart business decisions.
