This paper describes a component model suitable for development of Enterprise Application Integration Middleware in the industrial field. In this model, there are two types of subscription. In component level subscription, an interaction between components is defined by subscription to changes of component’s attributes or to occurrences of spontaneous events. A connector object attached to a subscribed component manages these inter-component dependencies. This results in independency of a component and enables localized modifications when systems are modified or extended. In application level subscription, adaptor components map inter-component dependencies into inter-application dependencies. In this paper, our proposed middleware, DiaSynapse, has been developed based on this model, and applied to the development of wide-area monitoring systems and network management systems.
