A FRAMEWORK FOR THE MODELING AND PROTOTYPING OF DISTRIBUTED INFORMATION SYSTEMS
Yi Deng, Shi-Kuo Chang · International Journal of Software Engineering and Knowledge Engineering · 1991
The major issues in designing Distributed Information Systems (DIS) include localization of control and data, inherent concurrency, intensive interactions among computation agents, history sensitivity, dynamic configuration and continuous system change and evolution. We propose a framework, called the G-Net model, for the specification, modeling and prototyping of DIS. The G-Net model not only provides a flexible notation to represent the executable specification of DIS through G-Net instantiation, but also offers a novel style of decentralized concurrent computation, allowing flexible inter-agent communication and interaction. A prototype of the G-Net framework has been implemented on workstations connected by a local network.
