What is Power BI?

Power BI is a leading BI tool for data analytics, creating data visualization, and preparing ad-hoc reports that give a multi-perspective view of the dataset. You can handle data from different sources after the cleaning (data cleaning involves steps like importing data, transforming data to tabular format, splitting up columns, removing unnecessary rows, and unpivoting the region columns) and integration (data integration means aggregating data from various sources and creating a single data model for analysis) process. It allows you to view, visualize and analyze the data. It uses powerful compression algorithms to import data in.PXIB file. It provides multiple software services, over 100 connectors, and a drag-drop feature, increasing ease of use. Dashboards generated are practical and easy to understand. Power BI uses Microsoft systems like Excel, Azure, and SQL, making it an easy win for those already using Microsoft products.

Power BI vs Tableau: Key Differences

Power BI is easy to learn as compared to Tableau.

• Power BI focuses on the “flow” to have a smooth and consistent user experience. On the other hand, Tableau focuses on coding to provide you with new visual effects which third parties create.
• Power BI uses DAX for calculating and measuring columns, while Tableau deploys MDX for measures and dimensions.
• Power BI offers PowerPivot dots (user to perform efficient data analysis) more user-accessible, but Tableau does not provide this.

Tableau or Power BI: Which one is better?

Both the tools have their own specific features. To select between these two, one needs to think about parameters like which person will use the tool (stakeholders or data analysts), what are their requirements, the size of the organization using the tool, the volume of data being used, etc.

Power BI comes up with intuitive features, therefore it is easy to learn. So it can be used by stakeholders who don’t have much knowledge as data analysts but want to do data analysis. In the case of Tableau, the interface is not very intuitive; therefore, quite challenging to learn. So, it can be used by data analysts who know data science and visualizations.

So, Power BI is better for its ease and Tableau for its speed and additional capabilities.
