Which of the following is a type of replication?
Options
- Update replication
- Read-only materialized views
- Multi replication
- All of the above
CORRECT ANSWER : Read-only materialized views
Discussion Board
Read-only materialized view
A materialized view can be either read-only, updatable, or writeable. Users cannot perform data manipulation language (DML) statements on read-only materialized views, but they can perform DML on updatable and writeable materialized views. Read-only materialized view eliminates the possibility of a materialized view introducing data conflicts at the master site or master materialized view site, although this convenience means that updates cannot be made at the remote materialized view site.
