Teradata CLIv2 for Workstation-Attached Systems - Teradata Database

Teradata CLIv2 for workstation-attached systems is a Teradata proprietary API and library providing an interface between applications on a TCP/IP-connected client and Teradata Database server. Teradata CLIv2 for workstation-attached systems can:

Build parcels which are packaged by Micro Teradata Director Program (MTDP) and sent to Teradata Database using the Micro Operating System Interface (MOSI).

Manage all interactions between the application and Teradata Database.

Provide an application with a pointer to data rows returned from Teradata Database.

MTDP

MTDP is the interface between Teradata CLIv2 for workstation-attached systems and MOSI. Functions of MTDP include:

Session initiation and termination

Logging, verification, recovery, and restart

Physical input to and output from the server

Note: MTDP does not control session balancing; session balancing on workstation‑attached systems is controlled by Teradata Database Gateway on the server.

MOSI

MOSI is the interface between MTDP and Teradata Database. MOSI is a library of service routines providing operating system independence among clients that access Teradata Database. With MOSI, only one version of MTDP is required to run on all workstation‑attached platforms.
