A cluster is a group of tables which share the same data blocks.
Clusters are an optional method of storing table data.
Cluster share common columns and are often used together.
It is a powerful method of storing and organizing data in the dataset into groups or clusters of similar data. Oracle physically stores all rows for each table in the same data blocks.

A view can be considered as a virtual table, It is like a stored query which treats the output of the underlaying query as a table.
