Introduction
In today's data-driven world, businesses generate massive amounts of data. However, raw data alone is not enough—it needs to be transformed into meaningful insights to drive decision-making. This is where Power BI, a leading business intelligence tool, plays a crucial role in data analysis.
Understanding Power BI
Power BI is a powerful analytics and visualization tool by Microsoft that enables businesses to collect, analyze, and present data in an interactive and user-friendly way. It simplifies complex datasets, making it easier for analysts and decision-makers to derive insights quickly.
