What is the process of combining two or more datasets into a single dataset?

Combining two or more datasets into a single dataset is data merging. It’s the process of bringing together the records and fields from multiple sources so you can analyze everything as one set. If the datasets share the same structure, you merge by stacking rows to extend the dataset. If they have related information but different columns, you align on a common identifier (like a customer ID) and bring the fields together to form one comprehensive table, handling any missing values as needed. Joining is closely related and often used inside databases to connect rows from two sources based on a shared key, which is a way to achieve merging, but data merging describes the broader idea of forming one dataset from multiple sources. Data fusion focuses on combining information from diverse sources to improve quality or create a richer view, and consolidation tends to refer more to gathering data into a centralized repository, not the specific act of creating a single merged dataset.
