摘　　要：大型管理信息系统由于研发、提供服务和管理、维护等原因,经常需要对其各数据库进行修改、改进和更新等操作。本文设计并实现了一个独立性、通用性较高、基于Oracle分布式数据库的数据库自动更新策略。实际使用表明:该策略大幅减少了人工乏味、重复性工作。大型管理信息系统的数据库更新方式实现了从手工作坊式更新到工厂化大规模更新的变革。Usually, modification, amendment, update and so on were necessary for multiple databases of a large-scale Management Information System for reasons like research, development, offering service and administration, maintenance. In this paper, an independent and universal Database Automatic Update Strategy based on Oracle distributed database was originally designed and achieved. Practical running demonstrate that laborious, tedious, repeating human labor could be greatly attenuated. The renovation that database update for large-scale MIS could be evolved from manual workshop to manufactory assembly came into reality.
