Teradata Access Modules
Teradata Access Modules are software components of the Teradata utility infrastructure that provide block‑level I/O interfaces to data residing on a specific external data storage device. Each access module is tailored to a specific type of external data storage device and can be dynamically linked to one or more Teradata utilities.
The Teradata Data Connector API is a shared component used by the Teradata Archive/Recovery Utility, Basic Teradata Query Utility, Teradata FastExport, Teradata FastLoad, Teradata MultiLoad, and Teradata TPump to perform data file I/O, either directly or via access modules.
