Geodatabase版本控制原理剖析

Principles of Geodatabase Version Control

随着地理信息系统的发展及其应用的不断扩大,多用户并发操作、长事务处理以及历史数据回溯管理成为大型空间数据库的基本要求,ESRI在面向对象地理模型(Geodatabase数据模型)中通过版本控制为空间数据库的上述要求提供了有效的解决方案。本文详细分析了Geodatabase版本控制基本原理,为建立、管理大型空间数据库以及研究开发全新面向对象空间数据库管理系统提供参考。

Along with the development of GIS, Multi-user concurrent operation, long transactions and historical data backtracking management have become the basic requirements of the large spatial database. Through Geodatabase version control, ESRI can provide effective resolution to meet above requirements. The basic principle of Geodatabase version control is analyzed in this paper, providing references for the construction and management of large spatial database and the development of a new object-oriented spatial database management system.
