A Unified Approach for the Integration of Distributed Heterogeneous Software Components
A framework is proposed for assembling software systems from distributed heterogeneous components. For the successful deployment of such a software system, it is necessary that its realization not only meets the functional requirements but also non-functional requirements such as Quality of Service (QoS) criteria. The approach described is based on the notions of a meta-component model called the Unified Meta Model (UMM), a generative domain model, and specification of appropriate QoS parameters. A formal specification based on Two-Level Grammar is used to represent these notions in a tightly integrated way so that QoS becomes a part of the generative domain model. A simple case study is described in the context of this framework.
