摘要
网络和信息技术的发展导致新的数据格式不断涌现,数据整合的要求日益迫切,为此提出一个基于虚拟集中方法实现的异构数据集成模型,可以实现分布、异构数据的一致性访问,并能保证数据的一致性、实时性和数据源的"即插即用",较好地解决了异构数据源的联合使用问题。最后给出了基于Java和XML技术的基本实现方法。
With the development of network and information technology,many new data formats come forth and data integration become more and more important,so a model of distributed heterogeneous data integration based on the method of virtual concentration is brought forward here.This model provides a unified way to visit the distributed heterogeneous data,it can also realize coherence and real time of the data and 'plug and play'of the data source.By this model united use of heterogeneous data source is satisfactorily implemented.A brief realizing method by the technology of Java and XML is given lastly.
