一个基于XML Schema的数据交换模型

A data exchange model based on XML schema

为了实现企业数据集成 ,建立了一个基于XMLSchema的数据交换模型 .该数据交换模型为 3层扩展模式 ,核心层为交换模型DEM ,初始层为公共组件 ,扩展层为专业模型 .该模型总体上分为数据类型、交换对象、计量单位、交换数据集 4个部分 .针对数据交换的特点 ,提供了一组适合数据库数据交换的数据类型 .交换数据集以实体为基础 。

We have established a data exchange model based on XML Schema for data integration for enterprises. The data exchange model falls into three levels: core level DEM (Data Exchange Model), initial level CM (common component) and extension level BM (business model). There are four parts in DEM that are data types, exchange objects, units of measure and exchange data set. Considering the characteristics of data exchange, a group of data types that is suitable to exchange data in database are defined. Based on defining entity, exchange data set defines general instance element and rules to extend entities.
