摘要
在Java分布式应用的三层应用结构模型,Servlet和可重用服务两种改进模型的基础上提出了多层应用结构模型。与上述其它模型相比,多层应用结构模型能够较好地符合分布式企业应用的实际需要,克服了以往模型的低效率、慢响应和难以存取本地资源等不足之处。文章详细描述了多层应用结构模型中各层的结构与功能。
This article introduces the software architecture of three-tiered Java-based applications on WWW,and presents some recent improved models,which are servlet model and service-based model respectively.After discussing features of these models,we advance and detail the new architecture model,named multi-tiered model,in which we primarily add a local service tier into the first three-tiered model.It is more suitable for real conditions of distributed apps than other models,in details,it's more effective and fast in response,and could access the local resources which can not be easily worked out in other models.
