摘    要:为解决国土系统间复杂而独立的各个业务系统之间的集成与共享中所存在的一系列问题,在传统土地信息系统集成模式基础上,提出了区域土地信息集成管理模型(Regional Land Information Integration Model,RLI2M)。通过基础数据与业务数据的分离,实现同一区域内不同业务系统在同一地图上的集成化应用。研究对数据仓库应用中的操作数据存储(Operational Data Store,ODS)进行扩展,根据国土资源应用特点提出土地信息操作数据存储(Land Information Operational Data Storage,L-ODS),将业务数据与基础数据实现隔离,利用面向事务处理方式提高了系统的响应速度,成功实现"一张图"应用与系统响应效率提高;通过统一建模语言(Unified Modeling Language,UML)中的消息/返回机制实现业务系统间的信息流与业务系统内的工作流的无缝集成,解决了传统集成方式中无法因数据结构与业务流程的差异,而对不同业务系统难以实现连接的问题。模型增强了跨系统间的集中监管,最大程度上避免了各业务系统各自监管所带来的弊端,对土地资源的集约化应用具有一定的技术参考意义。

关 键 词:国土信息系统  信息集成  操作数据存储(ODS)  通用建模语言(UML)

Abstract:This paper describes the design and implementation of Regional Land Information Integration Model(RLI^2M).Different Land Information System(LIS) cannot communicate with each other because of its inner workflows and data structure.Authors proposed a Regional Land Information Integration Model(RLI^2M) to solve the problems which is caused by numerous rigid land resources management laws and regulations.By separating fundamental geo-spatial data and business data,the model can bring out various business applications on one map.By enlarging the definition of Operating Data Storage(ODS),RLI^2M utilized a Land Information Operating Data Storage(L-ODS) to reduce redundant spatial data.Therefore,the developing of LIS would focus on business functions instead of data organization.The OLTP data structure design reduces the system respond time to a reasonable level.In addition,RLI^2M integrates different business systems by using the message/return mechanism in UML even though each of them is different in inner workflows and data structure.Compound message contains simple orders,geometry features as well as attribute tables.That means business systems can send complex signals to each other for communications.In that case,RLI^2M successfully strengthen central management which can prevent the disadvantages brought by independent business systems.This article also introduces an application based on RLI^2M which was implemented in Liuzhou City,Guangxi Zhuang Autonomous Region.
Keywords:Land Information System  information integration  ODS  UML
