Teradata is a Relational Database Management System (RDBMS), capable of supporting many concurrent users from various client platforms. Teradata is compatible with the ANSI standard and built completely on parallel architecture.

The Teradata RDBMS is linearly and predictably scalable in all dimensions of a database system workload (data volume, breadth, number of users, complexity of queries). The scalability explains its popularity for enterprise data warehousing applications.

Features

  • Acts as a "database server" to client applications throughout the enterprise
  • Uses parallelism to manage "terabytes" of data
  • Capable of supporting many concurrent users from various client platforms (over TCP/IP or IBM channel connections).

Utilities

  • Batch Teradata Query (BTEQ) - query tool to load data and export data off at a time
  • FastExport - to exports data from Teradata to a Flat file
  • FastLoad - loads huge amount of data from flat file into EMPTY tables
  • MultiLoad - to load multiple tables at one time from either a LAN or Channel environment
  • Teradata Parallel Data Pump (TPump) - loads data using multiple SQL sessions, using row hash locks
  • Teradata Parallel Transporter (TPT) - combination of BTEQ, FastLoad, MultiLoad, Tpump, and FastExport utilities
