摘　　要：主要介绍QT环境下通用数据库组件关键技术的研究。现有的QT嵌入式程序操作数据库步骤繁琐、代码冗余、性能低下,针对该问题,提出通用组件技术思想。组件由新型连接池模块、模板和规则库解析模块组成,新型连接池模块提升连接数据库的性能;模板极大精简了调用代码;规则库解析模块解析配置文件简化组件使用。最后把组件技术应用于真实生产环境,取得了非常优异的性能,产生了良好的效果。The paper mainly introduces the research on key technologies of universal database component under QT environment. Existing QT embedded program has the problems of numerous steps in database operation,redundant codes and poor performance. To address this issue,we suggest the idea of universal component technology. The component consists of the novel modules of connection pool,templates and rules library parsing modules. The novel connection pool modules enhance the performance of database connection,the template greatly simplifies the calling codes,and the rule base parsing configuration file simplifies the use of the component. Finally we apply the component technology in real production environment,it achieves excellent performance,and produces good effect.
