Distributed-application Development Based on Message Flows

摘要

Explosive increase in end-user computing on distributed systems requires that end-users develop application software by themselves. One solution is given as a method that one task in a domain model of cooperative work corresponds to one object in a computation model based on an object-oriented model. An end-user builds a domain model by using a visual tool at the first step, and then confirms the system behavior by simulation of the model. If some business components among the domain model have not implemented yet, these components should be developed. A script language is used for describing a new component. In addition, this language is used as a dscription language for an executable program which is automati- cally generated from a domain model while focusing on message flow. Therefore this language has the specific feature of describing a message flow as a message set for implementation of flexible work flow.
