TPF Application Requester

The TPF Application Requester (TPFAR) feature permits you to share data between a remote, DRDA level-1 compliant relational database and a TPF application using the common structured query language (SQL) interface. An LU6.2 connection is used to connect to a remote system. With TPFAR, a TPF application can directly access and retrieve or update the information residing on the remote system. TPF applications can be written in System/370 assembler language or the C language.

TPFAR uses the Distributed Data Management (DDM) architecture that allows an application program to work on data residing in a remote system. Built on top of DDM is the Distributed Relational Database Architecture (DRDA) which contains protocols for communication between relational databases.
