基于PHP的统一检索系统的设计与实现

Design and implementation of unitive search system based on PHP

通过设计统一检索系统过程模型,对网络数据库的检索步骤进行抽象,并对网络数据库进行描述,获取网络数据库的检索参数,实现在PHP5.0环境下网络数据库的统一检索,提高用户检索效率.采用PHP 5.0开发程序,优势在于优异的字符运算处理速度和可靠性,通过与Apache 2.0 Web服务器相结合使得统一检索系统具备良好的性能和稳定性.同时,通过构造一个合理的四元组模型实现统一检索系统完整的二次检索.

By designing a process model of unitive search system, abstracting the searching procedure of network database, characterizing the network database, and acquiring the search parameters of the net- work database, a unitive search system based on PHP5. 0 was implemented and the search efficiency was enhanced. The advantage of programming with PHPS. 0 was its excellent character＇s processing speed and reliability. The unitive search system possessed excellent performance and stability when combined with Apache2.0. Meanwhile, complete secondary searching was implemented by means of designing a reasonable quadruple model.
