摘要
介绍了GIS发展过程中出现的空间数据模型,以及不同空间数据模型的优缺点.对Geodatabase版本控制原理进行了分析说明,提出了使用版本控制来管理空间数据库的多用户并发操作、长事务处理,从而保证空间数据库的完整一致性.为建立和管理多用户的基于Geodatabase数据模型的空间数据库提供参考.
Design of spatial data model is critical to the construction of geodatabase.The spatial data models in the development of GIS were described,including their merits and demerits.The version control principle of geodatabase was also analyzed and explained.Using version control to manage the spatial database in multi-users' concurrent operation,and the long transaction was proposed so as to guarantee the complete uniformity of spatial database.The paper offers a reference to the establishment and management of spatial database based on geodatabase.
