Abstract: To improve damsafetymanagement level and knowthe damsafety information in time, more and more hydropower plants have finished or are about to construct damsafety information system. But the databases to be used are different, so that the compatibility of different database types during damsafety information systemconstruction should be considered. Considering the compatibility of different database types in database design, the dam safety information system was designed with object oriented method and encapsulated difference between different databases, then the information system could support different databases effectively.The operation at several hydropower plants showed that the system design was reasonable, operating performance was steady and the effect was favorable to support different database types.

摘要： 为了提升大坝安全管理水平,及时掌握大坝安全状况,越来越多的水电厂已经完成或即将进行大坝安全信息系统的建设。建设时, 各个水电厂所采用的数据库类型并不相同,因此,在开发大坝安全信息系统时就需要考虑到对多种数据库的支持。在数据库设计时就要考虑到对多种数据库的兼容, 采用面向对象方法设计大坝安全信息系统, 对不同数据库之间的差异进行封装, 可以很好地实现对不同数据库的支持。经过多个电厂的运行表明, 该系统设计合理, 运行稳定, 对于支持不同数据库类型效果良好。
