Materialized View Concepts and Architecture - Oracle

    https://docs.oracle.com/cd/E11882_01/server.112/e10706/repmview.htm
    Primary key materialized views that contain a selected class of subqueries can still be incrementally (or fast) refreshed, if each master referenced has a materialized view log. A fast refresh uses materialized view logs to update only the rows that have changed since the last refresh.

Understanding Materialized View Logs - Oracle

    https://docs.oracle.com/cd/E41507_01/epm91pbr3/eng/epm/pscw/concept_UnderstandingMaterializedViewLogs.html
    The Oracle database uses the materialized view log to refresh materialized views based on the master table. This process is called fast refresh and improves performance in the source database. A materialized view log can capture the primary keys, row IDs, or object identifiers of rows that have been updated in the master table.

    A materialized view is a database object that contains the results of a query. The FROM clause of the query can name tables, views, and other materialized views. Collectively these objects are called master tables (a replication term) or detail tables (a data warehousing term). This reference uses "master tables" for consistency.
