摘要

提出的异构数据集成系统框架包括源模式层、局部模式层、全局模式层和用户模式层.利用Web service接口完成从源模式层到局部模式层的转换

利用模式融合和冲突解决实现从局部模式到全局模式的转换

并嵌入数据查询过程.用户模式层作为全局模式层的一个子集

可以动态调整

方便集成数据的查询处理

还定义了一个基于XML的统一数据模型以支持异构数据的集成中的查询处理

提出了一个相应的查询处理过程.

Abstract

The heterogeneous data integration architecture of this paper includes fours level: source schema level

local schema level

global schema level

user schema level. We use Web service interface to complete the transformation from the source schema level to the local schema level. We implement the transformation from the local schema level to the global schema level using the mergence of different local schemas and the solution of confliction. The user schema level which can adjust according to the real-time situation dynamically is a subset of global schema level. We also define a XML based uniform data model to support the querying in the integration of heterogeneous data

and propose a query disposal process for the system.
