Tera Data – Course Content

Overview:

TeraData is a Relational Database Management System that is used to extract various types of data from multiple sources and converts, integrates and stores large scale data in a single place and in a common format and its data Consolidation make data available for analysis. The one of the biggest strength of the Teradata is the parallelism.

Training Objectives of TeraData:

Teradata is an enterprise software company that develops and sells a relational database management system (RDBMS) with the same name. It enables users on a workstation to easily access one or more Teradata Database systems for ad hoc queries, report generation, data movement and database administration.
