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.
