In Oracle database management systems:

Bulk Scanning: Involves efficiently reading large sets of data from the database in a single operation. It's useful for selecting and processing data from tables, reducing query overhead.

Bulk Loading: The efficient insertion of large data volumes into the database. It's commonly used during initial data population, data warehousing, or ETL processes to minimize insertion overhead.

These techniques enhance performance and efficiency when handling large datasets in Oracle databases.
