基于XML本源数据库技术的项目数据存储和交换研究

Research on storing and exchanging of project data based on native XML database technique

在21世纪新的制造模式下,项目数据需要在异构网络和系统下进行共享和交换,传统的数据库技术已不适应新的要求。提出了利用XML本源数据库存储项目数据,利用XML技术实现松散耦合的项目数据共享的方法。为了实现项目数据的正确性和完整性,保证数据共享过程中数据表达的一致性,建立了项目数据的标准XML模式,介绍了项目数据在NXD中存储的关键问题。

Project data of the new manufacture pattern needs be shared and exchanged in the heterogeneous networks and systems in the 21th century. The traditional database does not adapt to the new requirement. The method of storing the project data by using of Native XML Database （NXD） and sharing data by using of XML technique is brought forward. The standard XML Schema of the project data is established in order to ensure the validity and consistency when the data are shared. The key problems of storing the project data in NXD are introduced.
