Logical Structure

Applications that manipulate data on Teradata Database communicate with it indirectly by means of CLIv2. The application calls CLIv2, which acts as a subroutine of the application, sharing the same environment. CLIv2 executes as part of the same job, terminal session, virtual machine, or transaction.

Figure 1 illustrates the logical structure of the client-server interface.
