在对应用集成及其发展分析的基础上,将Web Services技术运用到空间信息应用集成,提出和建立了面向服务的空间信息应用集成框架,包括Web应用层、服务集成层、服务层和UDDI等4个组成部分。通过该框架,可以实现空间信息集成、服务集成和应用集成。论文解决了空间信息应用集成框架中的2个关键问题:(1)提出了分别从数据层次和业务层次对原有系统集成的解决方案,在数据层次上,提出了基于XML/GML的空间数据封装和基于Web服务接口的空间数据封装策略;在业务层次上,提出根据系统的功能模块和业务逻辑分别进行封装的策略;(2)提出了空间信息Web服务链接和服务组合的串联、并联和混联模式,通过三种模式服务链的设计,可以实现多个服务的链接和组合,从而完成空间信息以及应用集成。
Based on the analysis of application integration and its development, Web Services technology is applied to the application of spatial information integration, and a service-oriented spatial information application integration framework is proposed and established, including Web application layer, service integration layer, service layer and UDDI 4 components. Through this framework, spatial information integration, service integration and application integration can be realized. The thesis solves two key problems in the framework of spatial information application integration: (1) Proposed a solution to the integration of the original system from the data level and the business level respectively. At the data level, the spatial data based on XML / GML Packaging and Web services based on the spatial data encapsulation strategy; at the business level, proposed according to the system’s functional modules and business logic were packaged strategy; (2) proposed space information Web service links and service combinations in series, parallel and Hybrid mode, through the design of three modes of service chain, can achieve multiple services, links and combinations to complete the spatial information and application integration.
