| 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. |
