基于Oracle组件的数据采集与全文检索系统设计与优化
Design and optimization of data acquisition and full-text retrieval system based on Oracle component
摘要
Abstract
Proceeding from the requirements of data acquisition and full⁃text retrieval for the application system,and in combination with the access control,the design and implementation scheme of data acquisition and full⁃text retrieval based on Oracle Transparent Gateway and Oracle Text is proposed. Based on this scheme,the system structure design,collection storage and database design are conducted emphatically. The index creation and search procedure were realized. At the end of this pa⁃per,the optimization method of system performance is given,and the retrieval speed and precision ratio of the system are ana⁃lyzed. Now the system has been run on line,and achieved the using effect with high efficiency and stable running.关键词
