The integration model of heterogeneous data is divided into integration mode and integration style to do logic design. Function modules, such as database connector module, data integration module, timing updating module and setting module, are established to accomplish the heterogen-eous data integration tasks. 文章将异构数据集成模型分为集成模式和集成方式两方面进行逻辑设计,并建立数据库连接器模块、数据集成模块、定时更新模块和设置模块等功能模块,完成对异构数据的数据集成任务。
