摘　　要：为了提升网站开发数据库调用效率,提升数据库的安全性与应用效果,提出基于DAO模式的网站开发数据库调用方法。针对网站开发数据库各个应用层之间存在的耦合问题,将DAO模式设计到数据库应用程序中,达到降低程序耦合、减少数据库访问复杂性的目的;通过网站开发数据库的通信代价计算及并行化处理,完成网站开发数据库的任务调度分配,再采用粒子群算法对调度结果实行优化,以此提升网站开发数据库调用效率,实现网站开发数据库的调用。实验结果表明,通过对上述方法开展系统利用率测试、任务调度执行时间、数据库调用安全性测试,验证了上述方法的有效性。In order to improve the efficiency of website development database calls,as well as the security and application effect,a method of website development database calls was presented based on DAO pattern.For the coupling problem between the application layers of website development database,DAO pattern was applied into the database application to reduce program coupling and the complexity of database access.Based on the parallel calculation for communication cost of website development database,the task scheduling and allocation of website development database were completed.Moreover,the particle swarm algorithm was adopted to optimize the scheduling results,thus improving the efficiency of website development database calls.Finally,the website development database call was achieved.Experimental results show that the effectiveness of the proposed method is verified by testing the system utilization,task scheduling execution time,and database calling security.
