基于SCA的电子商务系统架构研究与设计

Research and Design of Electronic Commerce Systems Based on SCA

在信息普遍全球化的背景下,现代电子商务迅猛发展,其功能逐渐强大,但电子商务信息资源的离散性、异构性、分布性和不完整性等问题日益突出。为了解决上述问题,提出一种基于SCA框架的电子商务系统模型,通过设计系统逻辑架构,把电子商务系统中的不同模块由服务构件统一地封装起来,服务由接口定义,而接口包含一组操作,服务实现可以引用其他服务,使得系统各功能可以高效的衔接和耦合,从而具有扩展性和灵活性。实践表明该方案可以有效地对现有电子商务系统进行信息整合、信息交互和数据共享。

In the general context of globalization of information,modern electronic commerce is developing rapidly,its function is growing strongly.But problems of electronic commerce＇s discreteness,heterogeneous,decentralized and incompleteness increasingly prominent,as proposes a framework for electronic commerce system based on the SCA,through the design of logical structure of the system,the different modules of electronic commerce systems are uniform packaged through the service component.Services are defined by interface,and interface contains a set of operations,service implementation can quote other services,making the system function connect efficiently and coupling.So the system has feature of scalability and flexibility.Practice shows that the program can effectively respond to the existing electronic commerce system for information integration,information exchange and data sharing.
