Geodatabase模型的版本控制原理及应用

The fundamentals and application of version management in Geodatabase

地理空间数据模型设计是地理信息系统数据库建设的核心问题。本文介绍了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。并对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。

Designing of spatial data model is fundamental in database construction of GIS. The spatial data models appeared in development of GIS and the merit and shortcoming about them have been described in this paper, and the fundamentals of version management have been introduced. Using the version to manage spatial database in multi-user＇s concurrent operation, and the long transaction have been proposed, that guarantees the complete uniformity of spatial database. That would supply references to the establishment and management of spatial database based on C, eodatabase.
