In the same time , it explains that web service is the excellent frame for the development of a high scalable system . in this paper , we also studied the n - tier architecture based on component technology and how to implement business logic and data logic of his system using advance development method and midware technology based on model obtained from uml 论文也重点研究了基于webservice的分布式n层体系结构,以及如何利用当前先进的基于组件的开发方式和中间件技术,在uml建模的基础上,来具体实现his系统中的各种业务逻辑和数据逻辑,并对系统实现过程中的一些关键问题进行了深入阐述。
During more than half a century after the birth of computer , the methods of software development have changed continuously . in order to adapt to increasement of the application requirement , the academic circle advances the method of component based software development ( cbsd ) , and the industrial circle provides efficient technical support for this new method . there are three popular component models : com / dcom / com + , corba , ejb 在计算机诞生后的半个多世纪中,软件的开发方法在不断地发生着变化,为适应目前不断增长的应用需求,学术界提出了基于组件的开发方法,而产业界为这种新的开发方法,提供了比较有力的技术支持,现在比较流行的组件模型有com / dcom / com + , corba , ejb等。
Owing to its excellent adaptability to large angle - displacement between two transmission shafts and other characteristics such as large transmission ratio , terse mechanism , high transmission efficiency , cardan cross - pin spindles has been widely used as an important mechanical part in transport machines , metallurgy machines , petrolic machines , heavy machines , etc . as an effective and promising approach to resolve complicated development of modern software , component - based development ( cbd ) is put forward to change the present way of software development by producing software through assembling ready software components and its final target is to realize the industrialization of software development totally 十字轴式万向联轴器能够很好地适应传动轴间的较大角位移,而且具有传递扭矩范围大、结构紧凑、传动效率高、维修保养方便等特点,是一种重要的传动部件,因此在交通运输、冶金、重型机械等领域中得到广泛应用。基于组件的开发是近几年发展并日益成熟起来的一种软件开发新方法,其核心思想是以流水线方式、通过组装组件生产软件,从而容易实现软件开发的工业化。
Under the analysis of the deficiency of traditional b / s model and the tendency of enterprise computing development , this paper puts forward an intranet application system computing model based - on java and xml with the combination of the new software technology such as component - based development , java and xml <中文摘要> =本文分析了传统b / s模型的不足以及目前企业计算发展的趋势,结合当前软件界新出现的基于组件的开发、 java技术和xml等,提出了一种基于java和xml的intranet应用系统计算模型,并将其应用到了具体的工程实践中。
