Distributed Composite Objects: A New Object Model for Cooperative Applications

This paper introduces a new programming model for distributed systems, distributed composite objects (DCO), to meet efficient implementation, transparency, and performance demands of distributed applications with cooperating users connected through the internet. DCO model incorporates two basic concepts: composition and replication. It allows the representation of an object as a collection of sub-objects and enhances the object distribution concept by implementing replication at the sub-object level and only when demanded. DCOBE, a DCO-based programming environment, conceals implementation details of the DCO model behind its interface and provides basic mechanisms for object composition, distribution and replication of object state, consistency management, concurrency control and dynamic deployment of restructured objects.
