This paper mainly discussed how to store XML data document using relational database in ASCM system. Considering such characteristics as large quantities of data and fast updating in ASCM system on the basis of model mapping, this paper presented an inline schema mapping algorithm. Conversion process must consider hierarchy and ordering of XML data, and keep the XML schema information as much as possible to facilitate document reconstruction, realizing XML effective data storage in relational model and laying a foundation for establishing a unified ASCM system information sharing platform.%讨论了ASCM系统中XML数据文档关系化存储的实现.在模式映射的基础上,考虑到ASCM系统数据量大、更新速度快等特点,提出一种内联的模式映射算法.转换过程充分考虑XML数据的层次性、顺序性,尽可能多地保持XML模式信息以方便文档重构,实现了XML数据在关系模式中的有效存储,为建立统一的ASCM系统信息共享平台奠定基础.
