A Proposal for Evolution Driven Middleware Architecture for eBusiness Process Execution

摘要

This paper proposes the EDMA (Evolution Driven Middleware Architecture) for eBusiness process execution. EDMA is a middleware architecture which is adaptable for eBusiness evolution based on workflow management system and web services technologies. In order to build the highly adaptable architecture, we pay attention to an evolutionary model of eBusiness. We show characteristic phases of the eBusiness evolution and illustrate that EDMA is so adaptable that middleware implementing EDMA need not be replaced but instead be added with components to comply with the phases of the eBusiness evolution. In addition, we introduce our implementation of a workflow engine and researches related to EDMA.
