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 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.
