Loading only the records that were newly created or modified since the previous load-and applying those changes to an existing target dataset-is known as which type of data load?
Data archiving
Full load (complete reload)
Schema migration
Delta load
A delta load (also called an incremental load) captures just the changes-new, updated, or deleted records-since the last extraction and merges them into the target. A full or complete reload replaces the entire dataset, while schema migration and data archiving serve different purposes altogether.
