传统的地理信息网络应用系统开发方式由于其业务逻辑与表现逻辑结合过于紧密,代码重用性差,从而对大规模的应用系统开发造成局限性。本文面向应用系统快速构建,提出了基于服务的应用系统在线组装的思路,设计了"服务层-模型层-连接层-表现层"四层结构的应用系统组装器架构模型,并研制开发了New Map Zero Codes,实现了应用系统的可视化在线组装开发和管理维护。 更多还原

【Abstract】 In recent years,with the development of geographic information service,the geographic information is using widely in various fields of the society,there is an urgent need of constructing lots of special application systems.Besides,because of combination of the business logic and the expression logic is too close,the code re-usability is poor in the traditional development mode of geographic information web application system,what makes a limitation in the large-scale development of application s... 更多还原
