Teradata PT metadata describes the characteristics of objects, such as the following data and processing objects:

  • Data sources and targets
  • Table, column, and file formats
  • Operators

These descriptions provide the basis for all Teradata PT operations, as shown in the following table.

Metadata Use 
Metadata Type Purpose
Attributes of data sources and targets Determines the fastest access path for the Parallel Execution Plan
Table and column definitions Transforms, filters, or cleanses data

Teradata PT components, in effect, are metadata driven, as they are created, optimized, and executed based on guidance derived from the metadata definitions.
