【摘要】：海量增长的土地资源空间数据对跨部门、多用户的土地资源数据协同管理模式的有强烈的需求,目前成熟可行的跨部门、多用户的土地资源数据协同管理方案主要是依赖锁机制和多版本控制的,很少是面向土地资源管理业务特征和不同部门的多个用户之间相互交流、相互合作的土地业务管理方式的,而且锁机制和版本控制本身也存在着不可克服的缺陷。针对当前土地资源空间数据协同管理的研究所存在的不足,本文主要从空间数据库版本控制和锁定策略结合思路着手,进行基于版本控制与锁定策略结合的土地业务协同管理技术的研究,具体内容包括： 1、探讨土地资源空间数据的跨部门、多用户协同管理技术的具体内容,结合国土资源部门土地业务的特点,重点研究土地资源空间数据协同管理环境中版本控制技术中的权限控制问题和锁定策略中的粒度控制问题。 2、研究空间数据库协同管理的技术中的锁定策略与版本控制,比较两种思路的优势和不足,设计出一种面向多用户、多角色的版本号分配方案来解决协同管理中的版本冲突和用户等待时间的问题。 3、基于土地资源空间数据跨部门、多用户协同管理的研究现状,提出一种基于版本控制与锁定略策结合的土地业务协同管理模型,把版本控制和锁定略策两者的优势结合来完成土地业务的多用户协同管理。 4、基于对土地业务协同管理的相关研究,建立一个简单的土地资源空间数据管原型系统,验证模型的可行性。原型系统的工程实例表明本文研究的基于版本控制与锁定略策结合的土地业务协同管理模型可以充分结合版本控制和锁定策略两者的优势,实现土地资源空间数据在相同业务组内用户的乐观并发和在不同业务组内用户的悲观锁定,为目前各级国土资源管理部门的土地业务的跨部门、多用户的协同管理提供了一种有效的解决方案。
[Abstract]:The huge increase of land resources spatial data has a strong demand for cross-sectoral, multi-user land resources data collaborative management model, and now mature and feasible cross-sector, Multi-user cooperative management of land resources data mainly relies on locking mechanism and multi-version control, and rarely is oriented to the business characteristics of land resource management and the communication between multiple users in different departments. The cooperative land business management mode, and the locking mechanism and version control itself also has the insurmountable flaw. In view of the shortcomings of the current research on the cooperative management of land resources spatial data, this paper mainly starts from the combination of the spatial database version control and locking strategy. This paper studies the cooperative management technology of land business based on version control and locking strategy. The specific contents are as follows: 1. Discuss the cross-departmental and multi-user collaborative management technology of land resources spatial data. Based on the characteristics of land business in land and resources departments, this paper focuses on the rights control problem in the version control technology and the granularity control problem in the locking strategy in the cooperative management environment of land resources spatial data. 2. The locking strategy and version control in the cooperative management technology of spatial database are studied, the advantages and disadvantages of the two ideas are compared, and a multi-user oriented approach is designed. Multi-role version number allocation scheme solves the problem of version conflict and user waiting time in collaborative management. 3. Based on the research status of multi-user collaborative management of land resource spatial data, a land business cooperative management model based on the combination of version control and locking strategy is proposed. Combine the advantages of version control and locking strategy to complete multi-user cooperative management of land business. 4. Based on the research of land business cooperative management, a simple land resource spatial data management prototype system is established to verify the feasibility of the model. The engineering example of the prototype system shows that the cooperative land business management model based on the combination of version control and locking strategy can fully combine the advantages of version control and locking strategy. Realizing the optimistic users of land resources spatial data in the same business group and the pessimistic locking of users in different business groups are the cross-departments of land business of land resources management departments at all levels. Multi-user collaborative management provides an effective solution.
