基于数据集成的数据分析系统实现

A data analysis system based on data integration

随着信息技术的发展和信息资源的膨胀,企业对信息需求的程度越来越高。信息化已经从资源开发型转向信息管理型,"信息孤岛"的弊端越来越明显。数据集成技术是消除"信息孤岛"的有效方法。它采用物化视图的方式,通过包装器和集成器将异构数据源集成起来,解决数据集成过程中的部分数据冲突问题,实现了在数据集成上的数据分析。并且从整体构架上,考虑了系统的人机交互友好性。

At the present time, 'isolated islands of information' has brought about constantly because of different causes. With information technology development and information resource increase, information demand in enterprise is more and more higher. Informationlization has changed from resource development to resource management. The question of 'isolated islands of information' is clearer and clearer. Data integration is effective method eliminating for solving the question. A data analysis system based data integration is present in this paper. It uses materialized view to integrate heterogeneity data source using wrapper and integrator, and it resolves some data conflict. At last, it provides data analysis through the integrated database. It takes into account the human computer interaction from framework.
