Which action combines rows from separate tables based on a matching column to create a single dataset?
Data integration
Data normalization
Data sorting
Data merge
This technique joins datasets by matching a shared column (or key), forming one combined structure. Data integration is more comprehensive and does not necessarily rely on a specific matching key. Data normalization rearranges fields into standardized formats or structures. Data sorting alters the sequence of records but does not combine them from different sources.
