基于三层体系结构的ASP应用程序设计

Design of ASP Application Program Based on Three-layer Architecture

文章介绍了B/S应用程序的流行开发趋势三层体系结构应用程序的概念,三层体系结构具有的面向对象优点,封装性好,代码重用程度高;给出了三层体系结构的应用程序执行效率高,降低数据库的开销,并能简化ASP的程序开发的结论。结合一个实例创建DLL动态链接库作为商业层,介绍了三层体系结构的ASP应用程序构架。

Introduced the stream of designing B/S(browser/server) application program and the concept of three-layer architecture application program.Introduced the advantage that three-layer architecture face to the object and the good encapsulatin function and the high degree that the code again and again use. Gives out the conclusion that the application program of three-layer architecture carry out the high efficiency, and reduce use of the database's resources, and can simplify the development of the ASP program.Explains application program based on three-layer architecture through analyzing a sample of creating a DLL(dynamic link library) as the business layer.
