CONTEXTUAL COORDINATION FOR THE MAPPING OF DISTRIBUTED SYSTEMS ON OBJECT-ORIENTED SYSTEMS

Components of object-oriented systems have strong similarities with co mponents of distributed systems; objects can be viewed as loosely coup led computing entities similar to distributed processes, but objects g ranularity is generally different from process granularity. This preve nts a direct mapping between objects and processes during the implemen tation process. This paper presents a suitable coordination model, bas ed on hierarchical execution contexts, allowing to map object-oriented specifications into distributed systems. As a result, object-oriented systems can be mapped into distributed systems at the specification l evel, and we obtain a formal framework for understanding and implement ing distributed systems.
