基于Agent的异构数据库统一检索系统设计与实现

Design and Implementation of Integrated Retrieval System in Digital Library Heterogeneous Database Based on Agent

结合数字图书馆异地网络数据库的不可操作的技术特点,提出利用HTTP协议构建检索代理Agent实现异构数据库的统一检索,阐述利用Agent技术实现统一检索的系统体系结构和检索模型,讨论在VB.NET环境中系统主要功能模块的实现方法,最后对系统测试结果进行分析。

In consideration of the inoperability of digital library heterogeneous database, the thesis advocates using HTTP protocol to construct retrieval agent and realize integrated retrieval in heterogeneous database. The procedure medel and system structure of the integrated retrieval by agent is explained. The implementation method of the main system function modules in VB. NET environment is discussed. The result of the system test is analyzed.
