In Power BI, creating visuals is not the first step toward meaningful analysis. Before building reports, it is important to organize and connect your data properly. This process is known as "data modeling."
Data modeling helps you structure your data in a way that allows Power BI to perform accurate calculations and generate reliable insights.
What is Data Modeling?
Data modeling is the process of organizing data into tables and defining relationships between them.
In simple terms:
It connects different tables so they can work together for analysis.
For example, a Sales table can be connected to a Product table using a common column like Product ID.
Why Data Modeling is Important
Data modeling plays a key role in Power BI because:
- It ensures accurate calculations
- It improves report performance
- It enables proper filtering across visuals
- It helps in building scalable dashboards
Without proper data modeling, reports may produce incorrect or misleading results.
