基于协作者的异构数据集成模型研究

Research on heterogeneous data integration model based on mediator

为了保护企业既有投资,低成本实现异构数据源数据的有效集成,现对传统的"协作者"集成模型进行了扩充,变为语义处理、集成算法处理、优化和执行引擎4个模块。另外,针对异构数据集成的特点,定义了异构数据集成的数据结构,并利用Web服务合成技术对模型进行了验证。

In order to protect the existing investment and achieve effective integration of heterogeneous data sources data at lower cost, the paper expands the traditional mediator integrated model, which is composed by four modules including semantic processing, integrated algorithm processing, optimization and implementation of the engine. In addition, to meet the characteristics of heterogeneous data integration, the article defines the data structure of heterogeneous data integration, and certifies correctness of the model by using Web services composition technology.
