随着互联网技术的不断发展,基于网络(B/S架构)的应用程序越来越多。浏览器正在从信息浏览平台演变成网络程序开发平台。在如今的IT界里,许多计算分布在大量的分布式计算机上,而非本地计算机或远程服务器中,企业数据中心的运行也与互联网相似。一种能够集中能集中管理web应用程序,为企业提供网络解决方案的平台成为需要。所以本论文对webOS(网络操作系统)的进行研究并提供一种解决方案。
本论文的主要内容包括:
1) 在互联网上必布调查问卷,调查网民对基于网络的应用程序使用情况,以及用户对webOS的期待。
2)研究了基于prototype的面向对象的JavaScript的编程。在传统的JavaScript编程中都是基于过程的,本文件采用基于面向对象的使webOS的实现更加简单、方便,实现了webOS的模块化,增强了可扩展性。
3)对云计算技术进行了研究,阐述了云计算的三个重要特性:可扩展性、虚拟化、基于网络。云计算的核心以服务为中心,为用户提供数据存储。而webOS可以做为云计算的客户端平台。
4)本论文提出了一种基于Ajax技术的webOS系统的实现。在该系统中用户可以像使用本地计算机一样使用webOS。

With the continuous development of Internet technologies, network-based (B / S framework) is more and more applications. Browser views from the information into a network platform development platform. In today's IT sector, many in the calculation of a large number of distributed computers, rather than the local computer or remote server, the enterprise data center and the Internet is similar to running it. A centralized management can focus on to web applications, providing a platform for networking solutions become. Therefore, this thesis of webOS (network operating system) the conduct of research and provide a solution.
The main contents of this paper include:
1) on the Internet will cloth questionnaire survey of users of Web-based applications, as well as the expectations of users webOS.
2) research prototype based on object-oriented programming in JavaScript. In traditional JavaScript programming are based on the process, this document is based on object-oriented so that the realization of webOS more simple, convenient, modular webOS achieved and enhanced scalability.
3) Cloud Computing Technology conducted a study on the cloud computing three important features: scalability, virtualization, network-based. The core of cloud computing to serve as the center, to provide users with data storage. And can be used as webOS client cloud computing platform.
4) This paper presents an approach based on Ajax technology webOS system. In this system the user can use the local computer using the same webOS.
