Type System Overview

A type system is a framework that specifies characteristics of data types. The adapter type system must define the data types that the data source supports, the semantic category that matches the data type, and how they map to the data types that the Informatica platform supports.

The type system you define for an adapter consists of the following sets of data types:

Native types. Data types that the data source supports.

Semantic types. Semantic category that matches the native data type. For example, the semantic type Length matches the native data types, such as Char, Varchar2, Binary, Varbinary, Blob, and Clob.

Informatica platform types. Data types that the Informatica platform supports. The

Informatica Connector Toolkit

API uses ODBC as a model for describing Informatica platform data types.
