摘要
现代产品配置管理系统,数据库普遍存在数据结构复杂、存贮映射多变特性。分析了F/S和传统的两层Client/Server结构模式的不足,提出了通过采用中间件技术的多层模型来实现对底层数据库的访问,设计了采用中间层结构的数据库访问模型,为产品配置管理从人工方式向计算机辅助下的交互方式过渡提供了有力的技术保障。
Modern database of PCM system existed data structure complex and storage mapping changeable characteristics, the shortage of F/S and traditional two layers structure models were analysed. The methods that accessing the database through multi-layers model by using model layer technology was pointed out, the middie layer access model was designed, and a powerful technical guarantee is supplied for manual mode changing into computer- aided interactive mode.
