【摘要】 提出一种基于分层元数据的通用软件设计方法,并设计了基于分层元数据的通用软件结构模型。该模型的核心思想是在元数据层和应用数据层之间加入一个动态元数据层,以适应系统环境变化。通过在鞍钢铁运公司灵山现车管理系统项目中的具体应用和实现,证明该方法成功地解决了调车作业控制组件设计的通用性问题,有效地提高了软件的开发效率,降低了开发成本。更多还原

【Abstract】 In this paper it presents a design approach for general software and designs a framework model of it,all based on layered meta- data.The key notion of the model is adding a dynamic metadata level between the metadata level and the applying data level to adapt the change of the system environment.The practical application and realization in the AnGang Company in project of railway transportation man- agement system illustrate that this approach solves the general-utility question in designing control module of vehicle scheduling operation successfully,effectively enhances the software development efficiency,and reduces the development cost.更多还原
