摘要
本文研究并实现了分布式空间分析服务(DSAS)。提出了一种基于XML和Web服务构建DSAS的逻辑体系结构。首先对系统的体系结构进行了描述。然后简要介绍了如何用XML描述DSAS的元数据。然后重点介绍DSAS的Web服务接口。本部分研究了与DSAS接口相关的五个问题，包括接口的定义、接口的访问方式、地理空间特征的表示、访问DSAS的请求/响应消息(RRM)模式以及服务消费者与DSAS之间的交互方式。对每个问题的研究结果进行了详细的讨论。然后，基于Java Web Services和Java 2 Enterprise Edition (J2EE)给出了实现所提出的体系结构的物理体系结构。DSAS实例是根据物理体系结构构建的。最后，对所创建的DSAS实例的性能进行了分析。最后，得出了一些结论
Distributed spatial analysis service (DSAS) is studied and implemented in this paper. A logical architecture of building DSAS based on XML and Web services is proposed. The architecture is firstly described. After that, how to describe the metadata of DSAS with XML is briefly depicted. Web services interface of DSAS is then focused. In this part, five problems related with DSAS interface are studied, including the definition of DSAS interface, the access mode of DSAS interface, the presentation of geospatial feature, the request/response message (RRM) schemas for accessing DSAS, and the interaction way between service consumer and DSAS. The result of every studied problem is discussed in detail. Then, a physical architecture of implementing the proposed architecture is presented based on Java Web Services and Java 2 Enterprise Edition (J2EE). A DSAS instance is built according to the physical architecture. Finally, the performance of the created DSAS instance is analyzed. Finally, some conclusion is made
