云计算下异构数据集成模型的构建

为使用户能够将现有的应用系统向云计算环境迁移,将原有的异构数据处理无缝的映射为云计算环境下通用的数据服务和行为,从云计算和云存储的理论和模型出发,面向大规模的数据密集应用,针对各种异构数据库存储系统和云存储系统,构建云计算环境下异构数据模型,为用户提供透明、统一的异构数据集成和访问接口服务。实践证明:云计算下基于本体的异构数据集成模型的构建,可以为云计算环境下各业务应用提供统一的数据管理和处理方法,方便、快捷地实现异构数据统一的检索与查询以及业务应用所处理的各种异构数据之间实质性关联与映射。

Construction of Heterogeneous Data Integration Model on Cloud Computing

To ensure that users’existing application systems can be migrated to cloud computing platform,and the original heterogeneous data structure can be seamlessly mapped to the general service and behavior in the environment of cloud computing,this paper is involved in offering transparent integration of heterogeneous data and uniform interface service of access to users.By applying the theory and model of cloud computing and cloud storage,this service is aimed at building massive and dense data application,various heterogeneous DBMS and cloud storage system,and the heterogeneous data model for cloud computing.On the background of cloud computing,unified methods of data management and operation could be supplied through building heterogeneous data integrated model based on ontology.With the application of these methods,the uniform query and research for heterogeneous data can be completed easily,and the relation and mapping between various heterogeneous data can be built.
