What does the term 'merging' in Power BI often refer to?

Merging in Power BI refers to the process of combining records from different datasets into a single dataset, which allows for a more comprehensive analysis of the data. This typically involves blending two or more tables based on a common key or set of keys, enabling users to leverage related information from separate sources. By merging datasets, users can create a unified view of their data, ensuring that insights are derived from a holistic perspective rather than isolated datasets.

The act of merging is pivotal for data modeling and transformation, especially when dealing with multiple data sources that require integration for report generation. This capability enhances the analytical power of Power BI by allowing more complex relationships and insights to be created from joined datasets.

The other choices do not represent the concept of merging accurately. Creating new measures refers to defining calculations within a report, exporting involves saving reports into various formats, and disconnecting data sources pertains to managing data connectivity rather than combining records.
