TERADATA ARCHITECTURE  Teradata acts as a single data store, with multiple client applications making inquiries against it concurrently.  Instead of replicating a database for different purpose, with Teradata you store the data once and use it for all clients.  It provides the same connectivity for an entry-level system as it does for a massive enterprise data warehouse.  A Teradata system contains one or more nodes  A node is a term for a processing unit under the control of a single operating system.  The node is where the processing occurs for the Teradata Database there are 2 types of Teradata systems
  7. 7. Contd…  Symmetric multiprocessing (SMP): An SMP Teradata system has a single node that contains multiple CPU’s sharing a memory pool.  Massively parallel processing (MPP): Multiple SMP nodes working together comprise a larger, MPP implementation of Teradata. The nodes are connected using BYNET, which allows multiple virtual processors on multiple nodes to communicate with each other.  Teradata is the future of Data Mining. In future everyone we start using Teradata Database. Now it is costly, works are going on to reduce its cost. So it will reach to small business also.
  8. 8. TECHNOLOGY AND PRODUCTS  Its technology consists of hardware, software, database, and consulting.  The system moves data to a data warehouse where it can be recalled and analyzed. The systems can be used as back-up for one another during downtime, and in normal operation balance the workload across themselves.  Marketing research company Gartner Group placed Teradata in the "leaders quadrant" in its 2009, 2010, and 2012reports, "Magic Quadrant for Data Warehouse Database Management Systems".  Teradata is the most popular data warehouse DBMS in the DB-Engines database ranking.  In 2010, Teradata was listed in Fortune’s annual list of Most Admired Companies.

  12. 12. TERADATA AND BIG DATA  Teradata began to associate itself with the term, “Big Data” in 2010. CTO, Stephen Brobst, attributes the rise of big data to “new media sources, such as social media.”  The increase in semi-structured and unstructured data gathered from online interactions prompted Teradata to form the “Petabyte club” in 2011 for its heaviest big data users.  The rise of big data resulted in many traditional data warehousing companies updating their products and technology.  For Teradata, big data prompted the acquisition of Aster Data Systems in 2011 for the company’s MapReduce capabilities and ability to store and analyze semi-structured data.  Public interest in big data resulted in a 13% increase in Teradata’s global sales.

  14. 14. ADMINSTRATOR’S NEVER HAVE TO DO  Teradata DB’s never have to do the following tasks:  Reorganize data or index space.  Pre-allocate table/index space and format partitioning. While it is possible t have partitioned indexes in Teradata, they are not required.  Pre-prepare data for loading (convert, sort etc.,)  Unload/Reload data spaces due to expansion. With Teradata, the data can be redistributed on the larger configuration with no offloading and reloading required.  Write or run programs to split input source files into partitions for loading.  With Teradata the workload for creating table of 100 rows is the same as creating a table with 1,000,000,000 rows.  Teradata DBA’s know if the data doubles, the system can expand easily to accommodate it  Teradata provide huge cost advantages, especially when it comes to staffing DB admins.
