Answer Posted / guru
View: View is a virtual table, a query attached to it.

and returns rows.
A materialized view is a database object that contains the
results of a query. They are local copies of data located
remotely, or are used to create summary tables based on
aggregations of a table's data. Materialized views, which
store data based on remote tables are also, know as
snapshots.A materialized view can query tables, views, and
other materialized views. Collectively these are called
master tables (a replication term) or detail tables (a data
warehouse term)
