2.  Teradata is a relational database management system
(RDBMS) that drives a company's data warehouse.
 Teradata is an open system, compliant with ANSI
standards.
 It is currently available on UNIX MP-RAS and
Windows 2000 operating systems.

3.  Teradata is a relational database management system
initially created by the firm with the same name.
 It is a massively parallel processing system running a
shared nothing architecture.
 It is linearly and predictably scalable in all dimensions
of a database system workload

4.  Also explaining its popularity for enterprise data
warehousing applications.
 more than 60% of the world's most admired global
companies use Teradata technology.

5.  Teradata act as a single data store with multiple client
application.
 Using teradata store the data once and use it for all
clients instead of replicating a database.
 Teradata provides the same connectivity for an entry
level system.

6.  A teradata system contains one or more nodes
 A node is an term for processing unit under the
control of a single operating system

7.  There are two types of teradata systems.They are
 Symmetric Multiprocessing(SMP)-it has a single node that
contains multiple CPU's sharing a memory pool
 Massively Parallel Processing (MMP)- multiple SMP nodes
working together comprises a larger MPP implementation of
teradata

8. Teradata database is Linearly scalable -
Expand the database capacity by just adding more nodes to the
existing database.
Extensive parallel processing -
Teradata has a extensive parallel processing capacity.
Shared nothing architecture -
It has high fault tolerance and data protection.

9. Teradata development and DBA resources are harder to
come by and therefore more expensive.
Many key tech is still under the control of Teradata PS.
Teradata is for enterprise application, not as widely used as
Oracle or Sybase.
It is not suitable for small transaction OLTP databases.

10.  Teradata is the future of the data mining .
In future everyone we start using teradata database.
Now it is costly,works are going to reduce it's cost.
So ,it will reach to small business people also
