DSCM:a Service Component Architecture Model Supporting Dynamic Evolution
This paper studies dynamic reconfiguration technology in SCA(Service Component Architecture) in order to solve the SCA problem which is lack of dynamic management and evolution.A dynamic service component model DSCM is proposed based on OSGi(Open Service Gateway Initiative) and SCA.Within DSCM,application system's comprehensibility,reusability,expansibility,adaptability and dynamic evolution are enhanced by using Object teams as a technology infrastructure.Furthermore,DSCM can deal with the heterogeneity among diverse platforms and distributed runtime environment.It also supports POJO's (Plain Old Java Object) enhancement,which denote that DSCM is Universal and non-inbreak.
