摘　　要：在Arc SDE存档机制的历史数据管理方法基础上,提出了基于属性扩展的历史数据管理方法,并以浙江省基础地理信息系统为实例,从设计原理、更新流程、历史数据管理3个方面对该方法进行了详细介绍。研究认为,与Arc SDE存档机制相比,属性扩展的历史数据管理方法的优势在于能在多种库体中进行管理、回滚、备份和迁移,同时提高了数据更新的工作效率。On the basis of historical data management based on Arc SDE filing mechanism, this paper put forward a historical data management method based on attribute extension. And then, taking the fundamental geographic information system in Zhejiang Province for example, the paper described the management of this method from three respects, including designing theory, update process, historical data management in details. Comparing with the historical data management based on attribute extension and the historical data management based on Arc SDE filing mechanism, the former could management, rollback, backup and migration in multi database.
