基于XML原生数据库技术的维修保障信息存储和交换研究

摘要

异构网络和系统环境下数据的共享和交换是维修保障信息系统的一个关键问题,传统的数据库技术已不适应新的要求;提出了利用XML本源数据库存储维修保障信息,利用XML技术实现松散耦合的维修保障数据共享方法；为了实现维修保障信息的正确性和完整性,保证数据共享过程中数据表达的一致性,建立了维修保障信息的标准XML模式,介绍了维修保障信息在NXD中存储的关键问题,为新形势下维修保障信息的共享和交换提供了新的解决方案.%Maintenance support information needs be shared and exchanged in the heterogeneous networks and systems. The traditional database does not adapt to the new requirement. The method of storing the maintenance support information by using of native XML database (NXD) and sharing data by using of XML technical is brought forward. The standard XML Schema of maintenance support information is established in order lo ensure the validity and consistency when the data are shared. The key problems of storing the maintenance support information in NXD are introduced, It provides a new solution for the sharing and exchange maintenance support information under the new situation.
