【摘要】 土地是人类赖以生存和发展的基础,合理利用每一寸土地,使其发挥最大的经济和社会效益,成为土地管理部门的核心。随着我国社会经济和城市建设的飞速发展,一方面人地矛盾日益剧增,另一方面土地利用的不合理,地籍变更的频繁,都给土地管理工作带来很大的难度。建立功能完善的地籍管理系统是地籍管理模式的发展方向。地籍数据是地籍管理的核心内容,因此,地籍数据库设计就成为地籍管理信息系统的重点。本文分析了国内外地籍管理信息系统和地籍数据库模型的现状,提出了存在的问题,并结合当前地籍管理中的实际需求,提出了一种地籍业务联动更新的地籍数据库模型——对象-事件模型。该模型的设计思想是:根据面向对象的思想将地籍数据对象化,地籍业务事件化,通过建立对象、事件间的关联关系,实现地籍业务与地籍数据联动同步更新。根据对象-事件模型原理,对地籍对象、事件进行提取,并对地籍数据库进行了详细设计。最后,本文结合成都市地籍管理信息系统,对地籍数据库的建设进行了探讨,验证了该模型的可行性。更多还原

【Abstract】 Land is the foundation of human survival and development. Rational use of land resource and make them produce the best possible economic and social benefits have become the core of land management departments.In recent years, with the rapid development of economic and urban construction, the contradictions between people and land are becoming increasingly acute. On the other hand, unreasonable land utilization and frequently cadastral information changes bring difficult to land management. As a result, establishment of well-functioning cadastre cadastral management system is the development direction of management. Cadastral data is the core content of land management, therefore, the database design become the focus of cadastral management information system.This paper analyzes the present situation of domestic and international land management information systems and cadastral database models, and put forward some problems in application. In addition, this paper in light of the actual needs of cadastral management and design a new database model namely object-events model. The design idea of the model is that, cadastral data is treated as object, as cadastral operation event, through the establishment of the target relationship between the object and event and achieve cadastral operation and data update in synchronism. According the model theory, this paper detailed the methodology for cadastral database design.In the end, this paper deeply discussed the design of cadastral database combining Chengdu cadastral management information system. Preliminary results demonstrated the feasibility of this method.更多还原
