The ToolTalk® service is used by independent applications to communicate with each other without having direct knowledge of each other. Applications communicate by creating and sending ToolTalk messages. The ToolTalk service receives these messages, determines the recipients, and then delivers the messages to the appropriate applications. See Figure 1.1.1. Before modifying your application to use the ToolTalk service, you must define (or locate) a message protocol: a set of ToolTalk messages describing operations that applications agree to perform. The message protocol specification includes the set of messages and how applications should behave when they receive the messages.
