【摘要】 以中间件技术为基础框架的多层体系结构愈来愈得到重视,但应用范例较少。该文首先介绍了多层应用体系结构,然后以Tuxedo为例详细阐述了基于中间件的多层体系结构框架,最后在应用实例中,针对三种不同要求分别讨论了集中型、数据分布型和应用分布型多层体系结构。研究成果具有较大的应用价值。更多还原

【Abstract】 The multi_tier architecture based on middleware is getting more and more attention,but the application paradigm is lacking.First,this paper introduces multi_tier application architecture.then it explains the frame of multi_tier architecture based on middleware,citing Tuxedo.finally in application instance,it discusses three types of multi_tier architecture:centralization paradigm,data distributed paradigm and application distributed paradigm,according to three different requirements separately.更多还原
