Research On SMEs-Oriented Lightweight Service Component Architecture Design And Application

SOA (Service-Oriented Architecture) is a new architecture model that makes software application program to be the reusable business services. It predigests the developing of enterprise application to integrate and reuse business service. The core of SOA application is the design of service component. SCA (Service component architecture) is a type of SOA programming model. By SCA, clients can create new service or translate the existing IT resource into reusable service. These services can quickly adapt the changing business requirement and never mind which programming language and running workplace. This reduces the complexity of application developing.Firstly, by discussing SOA and SCA, this paper analyzes some problems in the SMEs' application, like Business Process Changing; Cost Pressure; Universal Requirement and Reusable. It discusses the application of SCA in the SMEs and the design objective of SCA in the SMEs.Basis on these, this paper researches the SCA and discusses three core components in SCA like Component, Composite and Domain. It also discusses three invoking methods like Single-way invoke, Delay-response invokes and Require-call back. By the SCA design, this paper discusses the application project of SCA, and then researches the design of project's architecture. It exhibits an integrated application project by discussing the design and implementation of service component, the implementation and rebuild of business process and the calling way of business process.At last, by the developing of CEA Measuring Management System and Global Shipping Logistic Management System, it discusses the real application of SCA and the application project of SCA, and validates the practical value of SCA and the application project of SCA.
