Power BI dashboards can integrate data from multiple sources using Power BI’s built-in data connectors. These connectors allow you to pull in data from various platforms such as SQL databases, Excel files, cloud services, and third-party APIs. Power BI’s data modeling features enable the creation of relationships between these data sources, allowing for unified analysis and reporting. This integration ensures that dashboards provide a comprehensive view of business operations, bringing together disparate data points into a single, cohesive interface. This capability is crucial for businesses that rely on multiple systems for their data.
