In computing, a materialized view is a database object that contains the results of a query. For example, it may be a local copy of data located remotely, or may be a subset of the rows and/or columns of a table or join result, or may be a summary using an aggregate function.
What is Materialized View?
In Database, a materialized view (MV) is a database object that stores the results of a query. It can be a copy of data from a remote location, a subset of rows and/or columns from a table or join result, or a summary using an aggregate function. MV is normally used for frequent queries of based tables.
