Designing and implementing inter-client communication in the O2 object-oriented database management system
One of the requirements for an object-oriented database to support advanced applications is a communication mechanism. The Inter-Client Communication Mechanism (ICCM) is a set of data structures and functions developed for the O2 database, which provides this kind of service. Communication is achieved through shared persistent objects, implementing the basic idea of mailbox. One to one connections are established between different processes accessing the database. Methods and data structure defined in the ICCM support connection set-up, disconnection, and all the basic data transfer facilities. In this paper, we describe the concepts of the ICCM and an overview of its implementation.
