摘要
基于ArcSDE的版本控制机制,研究了多用户状态下对存储于Oracle数据库中的空间数据及其属性信息进行并发编辑控制的策略。针对不同的工作环境,提出两种不同的处理策略,即在线编辑控制和离线编辑控制。实际工程项目中的实现和验证表明,这两种策略虽各自存在优缺点,但均为有效的解决方案。
This paper proposed a strategy of multi-user parallel edit for spatial data which was stored in Oracle database based on ArcSDE version mechanism. With respect to various environment, two different modes, on-line edit pattern and off-line pattern, were raised. A practical application indicates that the two patterns prove their effectiveness ahhough with advantages and disadvantages respectively.
