Chapter 6 section 2{0}
The article I read I found on Oracle Magazine. Apparently Oracle has developed a Oracle Exadata Database Machine. They introduced it to the world at the Oracle Open World, San Francisco September 20, 2010. The Oracle Exadata Machine is really an integration of software and hardware by Oracle. They feel if they own both the hardware and software they can reduce cost of install and reduce cost of specialized maintenance. Whats really cool about Oracles Exadata machine is that it offers organizations a different way to make strategic decisions. It can handle the toughest data warehousing and OLTP requirements while simultaneously making it easier than ever before to truly understand and analyze the wide range of data that organizations are collecting(Kelly,2010). The unique technology advantages of the Exadata Database Machine is that it pushes SQL processing to the Exadata Storage Server by doing this all the disks can operate in parallel, reducing database server CPU and using much less bandwidth to move data between storage and database servers.(OracleDataSheet, 2010). Oracles Exadata machine features include uncompressed user data capacity of 100 TB per rack, a uncompressed I/O bandwidth of up to 50 GB/ second per rack, 5.3 TB of Exadata Smart Flash Cache, 2 database servers, and128 cpu cores and 2 TB of memory for database processing. (OracleDataSheet, 2010).
This article relates to the topic being discussed in class in many ways. Chapter 6 is all about databases and optimizing the database retrieval process. This Machine can help many businesses improve there Online Transaction Processing (OLTP) and Data Warehouse capabilities and processing speed. Section two in the chapter briefly discuses data marts. The Oracle Exadata Machine delivers that strategic information to the data marts. This new database machine should improve the way Data Warehouses store and retrieve information.
