Overview
Introduction
The RPC Broker is a client/server system within VA's Veterans Health Information Systems and Technology Architecture (VISTA) environment. It enables client applications to communicate and exchange data with M Servers.
This manual describes the development features of the RPC Broker. The emphasis is on using the RPC Broker in conjunction with Borland's Delphi software. However, the RPC Broker supports other development environments.
This manual provides a complete reference for development with the RPC Broker. For an overview of development with the RPC Broker component, see the "RPC Broker V. 1.1 Getting Started with the Broker Development Kit" manual.
This document is intended for the VISTA development community and Information Resource Management (IRM) staff. A wider audience of technical personnel engaged in operating and maintaining the Department of Veterans Affairs (VA) software might also find it useful as a reference.
