1. Introduction: The BI Landscape in 2025
The business world in 2025 is powered by data like never before. Whether you’re tracking customer behavior, analyzing performance metrics, or forecasting revenue trends, one thing is clear data is the new currency. But without the right tools to interpret it, data is just noise. That’s where Business Intelligence (BI) tools come in.
BI platforms have become central to every organization’s growth strategy. They help turn complex datasets into clear insights, streamline decision-making, and foster data literacy across teams. But with so many options available, choosing the right BI tool can feel overwhelming.
