【摘要】 从系统架构和功能需求分析入手,介绍了基于CORBA/WebService技术开发的PDM图档管理系统,着重阐述了系统开发中的关键技术:IDL到WSDL的映射和CORBA对象的WebService封装。针对CORBA现有IDL到WSDL映射规范中对复杂数据类型和接口继承的支持不够的情况下,提出了可以满足实际应用需求的映射规则,并实现了一个映射编译器——IDLW,从而实现了Internet范围内的图档数据访问和管理。更多还原

【Abstract】 Beginning with the analysis of system design and functional requirement,a PDM drawing and document management system which based on CORBA/Web Service is introduced.Making a emphasis on key technology: mapping IDL to WSDL and encapsulating CORBA object with Web Service.To solve the problem of mapping complex data type and interface inherent in IDL to WSDL which is not yet specified by OMG,a set of mapping rules is presented and a compiler——IDLW is implemented,thus making the system can be accessible on internet.更多还原
