【摘要】 数据集成平台的作用是提供一个访问异构数据源的统一接口,使用户或处理数据的业务系统不必考虑数据模型的异构性、数据抽取、数据合成等问题。异构数据源集成问题是数据库领域的经典问题,研究者们在数据集成领域取得大量的研究成果。但是这个研究领域是如此的丰富,加之总有新的技术与它结合,所以仍有大量的问题期待人们解决。随着Internet/Intranet技术的不断发展,WEB技术已变得非常成熟,现在一个明显的趋势是所有的业务应用向WEB靠拢。利用WEB技术构建数据集成平台的现实意义非常大。本文以电信领域话单数据现状和对数据集成的要求为基础,进行基于WEB技术的数据集成研究。在分析比较已有数据集成方法和体系结构特征的基础上,设计了基于WEB的电信话单集成平台。在设计实现此平台的同时,提出了一种新的集成体系结构,在集成领域内解决了两种经典体系结构的对抗问题;着重分析了模式集成与数据展现。在模式集成中,使用XML描述数据的模式,使得模式集成变得简单。在数据展现研究中,选择了以WEB技术为基础的B/S结构作为集成平台的展现结构。提出了三层结构的展现机制对数据进行展现,满足了集成平台对数据展现的可扩展性、灵活性、个性化等要求。本文工作的意义在于解决了文件级别的异构数据源集成问题,设计的集成平台向用户或其它业务系统提供了统一的、规范的XML数据服务,为在电信领域建立一个通用数据访问底层架构奠定基础。更多还原

【Abstract】 The goal of a data integration platform is to provide a uniform interface to a multitude of data sources. Using the interface users don’t need to consider the problem about model heterogeneity, data extracting and combination, etc.. The problem of data integration is one of the ad hoc old problems in database community. Researchers have gained a lot in this field in these years, but it is such a rich area that there are still a lot of problems waiting for solutions, especially when more and more new techniques joined the area.As the development of the Internet/Intranet technology, WEB technology has become well-developed technology. An apparent trend is that almost all business applications use WEB technology. The practical significance of using WEB technology to build data integration platform is very great.This paper discusses the issue of integrating telecommunication call-list data based on extensive analysis and research work. We use WEB technology to design the data integration platform framework based on analysis and comparing the existent data integration methods and the characteristics of architecture. Meanwhile, we design a new architecture of data integration. The new architecture resolves the clash between the two classic architectures. We mainly analyze schema integration and data display. In the research of schema integration, using XML to describe the schema of data, make schema integration become easy. In the research of data display, we use B/S structure as the structure of the data display. We designed a three tier architecture in the data display module which make the data integration platform has the characteristics of expansibility, flexibility, individuation.The significance of this paper is to resolve the problem of heterogeneous file data integration and design a platform framework to provide a uniform, reputable XML data service for users or business system. Our work can be used to build a universal data access infrastructure in telecommunication domain.更多还原
