In this paper, we modeled the dynamic operations of the e-commerce trade platform using the Web service and work flow technologies, turned the functional modules of the platform into applications in the Web service system, then modularized the trade interface and recorded the trade processes using the work flow modeling method.%在Web计算机服务和工作流技术下,对电子商务交易平台动态工作提出建模,交易平台中的功能模块将会变成Web Service中的应用程序,对交易界面进行模块化分割,用工作流建模的方法对交易流程进行记录,从而通过流程中任务的绑定,实现交易平台的动态构建。
