【摘要】 随着企业规模的不断扩大,一个单独企业,每个部门或单位就是一个数据源,每个数据源都可能是异构的,它们构成了企业的异构数据源。这必然导致越来越多的企业应用需要访问各种异构数据源,为了满足这种需求,必须研究出能够支持异构数据源数据整合的系统。为了解决企业信息异构的问题,实现企业间资源共享和信息互访的目的,本文提出了基于中间件技术的数据整合方案。其中,中间件技术用CORBA和XML实现。CORBA(通用对象请求代理体系结构)是一种分布式对象技术,利用CORBA的核心部件ORB可以实现异构数据源的透明互访;XML(可扩展标记语言)是一种标记语言,通过与关系型数据模式的转化,可以消解数据源数据模式的异构。更多还原

【Abstract】 With the sustaining development of the scale of company, in a single company, every department will become a data source. And each data source has its own framework; all of these data constitute the different data source of the company. This phenomenon will lead to the requirements that more and more company need to visit all sorts of data source. In order to meet this demand we need the system, which can support the integration of the different data source.To solve the problem of heterogeneous information between enterprises, and realize the data sharing, this paper put forward the scheme of data integration based on middleware technology. There we using CORBA and XML technology to realize the middleware. CORBA (Common Object Request Broker Architecture) is a technique of distributed object, it can implement the transparent exchange visits of distributed heterogeneous data source by the use of the core of CORBA, ORB; XML (eXtensible Markup Language)is a kind of meta-markup language, which provides a format that describe data. Through the transform between XML and relationship data pattern, different data pattern can be unified and the heterogeneity of data source can be cleared up.更多还原
