The Oracle Exadata Database Machine retrieves data from disks in response to a SQL statement
in the same way as a standard database server.
A.
True
B.
False
Explanation:
The Exadata Database Machine technology can retrieve the data in a more efficient
way compared to a standard database server.
When using Exadata, much SQL processing is offloaded from the database server to the Exadata
cells. Exadata enables function shipping from the database instance to the underlying storage in
addition to providing traditional block serving services to the database. One of the unique things
the Exadata storage does compared to traditional storage is return only the rows and columns
that satisfy the database query rather than the entire table being queried.
