摘　　要：在综合分析海量数据库检索系统应用及存储环境的基础上,提出了一个集群环境下的个性化检索系统模型,采用Oracle RAC技术实现数据库数据的并行处理,通过兴趣获取模块获得用户兴趣,实时动态追踪兴趣动向,实现个性化检索.在此基础上完成了某市基于超大型数据库的专利信息检索系统平台的设计与实现.Based on synthetically analyzing the application and data-stored environment about a super lage-scale database retrieval system, a system model is proposed, which using Oracle RAC database technology to implement parallel computing. Personalized retrieval is realized through the interest accessing module, which gets customer＇s interests and dynamically tracks the trends of customers＇ interests. Based on above, we have completed the design and implementation of a patent information retrieval system based on super large-scale database.
