The main achievements are as fellow : for effective sharing and rapid integration of decision support resources in network environment , dss layer model ( dsslm , including representation , plan , instance and server ) . decision resources interface specification , the integration & running protocol of decision resources and the architecture of integration dss have been achieved . the architecture composites many decision support technologies , which defines the relation among the integration protocol , the interface specification and decision resources servers 作者完成的工作和取得的创新成果如下：为了实现网络环境下决策资源的有效共享和快速集成，作者提出了dss层次模型( dsslm ，包括表现层、方案层、实例层、服务器层) 、决策资源接口规范、决策资源集成和运行协议以及能够集成多种决策支持技术的综合决策支持系统体系结构，它明确了各种决策支持技术之间的集成关系，明确了网络环境下资源运行协议、接口规范与服务器之间的关系，对于网络dss的开发和应用具有积极的意义。
Nowadays the technology of j2ee has been applied widely in many fields . from the viewpoint of the designment , the application of j2ee technology can be divided three layers architecture , which are view layer , business layer and data persistence layer 。 these three layers are alternatively supported by the techonology of web and ejb . the technology of web supports the view layer , meanwhile , business layer and data persistence layer are supported by the techonology of ejb . with the rapid and constant development of the techonology of j2ee , there are a lots of lightweight frameworks corresponding to every layer of the designment of j2ee technology 。 in fact , the development of lightweight framework boosts the development of j2ee technology and lightweight framework has been the basic of the following architecture of j2ee technology J2ee的应用越来越广泛, j2ee应用从设计上可以分为三层:表示层、业务层和数据持久层。在这三层上与之对应的j2ee技术为web技术和ejb技术, web技术实现表现层,而ejb规范负责业务层和数据层。由于j2ee技术的不断发展,在j2ee设计的各个层次现在都有对应的轻量级框架出现,轻量级框架的发展极大了推动了j2ee技术的发展,轻量级框架技术已经成为了下一代j2ee构架的基础。
