基于J2EE的分布式地籍变更系统设计与实现

鉴于当前地籍信息系统建设转向Brower/Server模式的应用需求,提出基于J2EE架构进行分布式地籍变更的思路;通过对分布式地籍变更的功能分析,指出分布式地籍变更的功能需求,并给出了相应的解决方案:采用XML文档对象进行地籍变更数据传输,利用OracleSpatial进行地籍数据的存储,应用构造点方法进行地籍变更实现;在此基础上提出了分布式地籍变更系统的总体框架与逻辑模型;最后对地籍变更的构造点方法实现算法、地籍变更数据传输的XMLSchema定义、应用服务器端EJB设计与数据库服务器端的存储过程开发进行了探讨,并最终实现了分布式地籍变更系统。

The design and realization of distributed cadastral alteration system based on J2EE

According to the applied requirement of turning toward the pattern of the Brower/Server from the construction of the cadastral information system currently, the paper presents the thought of the distributed cadastral alteration based on J2EE.By analyzing the function of the distributed cadastral alteration,this paper points out the function requirement of the distributed cadastral alteration, and bring forward the corresponding solutions:Using the XML documents object to transmit the data of the cadastral alteration;②Adopting the Oracle Spatial to store the cadastral data;③Applying the method of the structure points to realize the cadastral alteration.Based on the above mentioned, the thesis puts forward the general framework and logical model of the distributed cadastral alteration system.Finally, the paper discusses the algorithm of the cadastral alteration based on the structure points method,the definition of the XML schema of the data transmission of the cadastral alteration,the design of the EJB on the application server and the development of the storage procedure on the database server in detail,and realizes the distributed cadastral alteration system at last.
