What is the primary focus of datasets in Power BI compared to data sources?

The primary focus of datasets in Power BI is that they involve more structured and analyzed data. Datasets are essentially collections of data that have been transformed and organized in a way that enables effective reporting and analysis. They are derived from one or more data sources, which can include everything from databases and online services to spreadsheets and flat files.

In Power BI, the process of creating a dataset involves importing data from these sources and then performing various transformations, calculations, and aggregations to prepare the data for visualization. This structured and analyzed data allows users to create insightful reports and dashboards, making it possible to derive meaningful insights from raw data.

While other response choices offer insights about aspects of datasets and data sources, they do not accurately capture the distinctive nature of datasets in Power BI as focused on the transformation and analysis of data, which is essential for effective data visualization and reporting.
