摘　　要：如何将异构的数据源集成,为用户提供统一的查询服务,是目前数字图书馆广泛面临的问题。本文针对此问题提出了采用基于虚拟数据库技术的信息集成系统架构,并采用Web Service技术将不同数据源的集成以服务的方式把集成接口暴露出来,实现具有松散耦合性、易于维护的数字图书馆信息检索系统。Howto integrate heterogeneous data sources to provide users with a unified inquiry service, which is the wide range of problems faced by digital libraries. This paper proposed for this problem using the information integration system architecture based on a virtual database technology. Useing Web Service technology, the integration of different data sources to serve the way the integration interface was exposed, to achieve a loosely coupled nature, easy to maintain the digital library information retrieval system.
