基于单件模式的数据库连接组件的设计

Design of data bank link packages based on single-card model

结合单件设计模式的特点,和组件的技术,建立了一个数据库连接组件,通过调用该连接组件,可以实现应用程序中的所有访问数据的操作共用一个连接的目的,从而减轻了服务器的负担,提高了程序性能。经实际测试,该设计达到了预期的效果。

Based on the characteristics of the single - card design model and the technology of package, we established a data bank link package. By regulating the package, we can realize the goal of sharing the one link in the operation of all visit data of application program so as to reduce the burden of server and improve the program function. After being tested, the design has reached the designed effect.
