Power BI vs Power Query: Which is Better?
Power BI and Power Query are both Microsoft tools used for data analysis, but they serve different purposes. Power Query is a data transformation tool used to clean, shape, and load data, whereas Power BI is a complete business intelligence (BI) platform for data visualization, reporting, and analysis.
This comparison will help you understand their differences and decide which tool is better suited for your needs.
1. Overview of Power BI and Power Query
What is Power BI?
Power BI is a business intelligence tool that helps users create interactive dashboards and reports. It integrates with various data sources and provides real-time insights through advanced visualizations and analytics.
Key Features of Power BI:
