The Oracle Exadata Database Machine is a database machine that provides extreme performance for both online transaction processing (OLTP) applications and data warehousing (DWH) systems.

Exadata was designed to address the most common bottleneck with very large databases: the slow speed & sometimes inability to move sufficiently large volumes of data from the disk storage system to the database server. Oracle, in the normal course, does provide intelligent caching technology to solve this problem. But as database sizes have outstripped the caching capabilities, Oracle came up with Exadata.
