6. 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. 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. 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.
9. ACTIVE ENTERPRISE DATA
WAREHOUSE
Teradata Active Enterprise Data Warehouse is the platform that runs the Teradata
Database, with added data management tools and data mining software.
The data warehouse differentiates between “hot and cold” data – meaning that the
warehouse puts data that is not often used in a slower storage section.
Teradata Database 13.10 was announced in 2010 as the company’s database software
for storing and processing data.
Teradata Database 14 was sold as the upgrade to 13.10 in 2011 and runs multiple data
warehouse workloads at the same time. It includes column-store analyses.
Teradata Integrated Analytics is a set of tools for data analysis that resides inside the
data warehouse.
10. BACKUP, ARCHIVE, AND RESTORE
BAR is Teradata’s backup and recovery system.
The Teradata Disaster Recovery Solution is automation and tools for data recovery and
archiving. Customer data can be stored in an offsite recovery center.

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.
13. Competition
Teradata's main competitors are similar products from vendors such as Oracle, IBM,
Microsoft and Sybase IQ.
Also,competitors include data warehouse appliance vendors such as Netezza (acquired
in November 2010 by IBM),DATAllegro (acquired in August 2008 by Microsoft), ParAccel,
Greenplum (acquired in July 2010 by EMC), andVertica Systems (acquired in February
2011 by HP), and from packaged data warehouse applications such as SAPBW and
Kalido.
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.
