It is one of the most popular tools in the market, and its demand has increased exponentially over the years. Aspiring data scientists must be familiar with this tool as it can significantly help them in their field of work. In this blog, we will be discussing eight essential facts about Power BI that every aspiring data scientist should know.
Power BI is a Microsoft product:
Power BI is a business intelligence tool developed by Microsoft. It is a cloud-based service that allows users to connect and analyze data from various sources. As it is a Microsoft product, it seamlessly integrates with other Microsoft products like Excel, SharePoint, and Dynamics 365.
Power BI provides a range of data connectors:
One of the significant advantages of Power BI is that it provides a range of data connectors. It supports a vast number of data sources like Excel spreadsheets, SQL Server, Oracle, MySQL, and many more. With these connectors, users can easily connect to different data sources and combine data from various sources to get insights.
Power BI provides a range of data visualization options:
Power BI provides a range of data visualization options that make it easy to create beautiful and interactive reports.
