User Management Module And Message Management Module Design And Implementation In Web Cloud System

The WebOS is a browser-based system, similar to the desktop system. Due to thefeatures as thin client paradigm, WebOS can be used in any device capable of running abrowser，which make it have very broad applications. In this thesis, we focus onresearching of how to transfer asynchronously the requests and resonses in WebOSdesktop system, and how to implement a no refresh effect desktop, and also onresearching of providing what kind of application programming interface fordevelopers.We also focus on designing and implementing a Web desktop system wementioned above in this thesis, including its foreground communication module,background message management module, user management module, and processmanagement module. We also describe the design of the system architecture, and thedesigning and implementing methods of the important modules, on the basis ofanalyzing of the existing Web desktop system at home and abroad.In this thesis,We design the foreground desktop by a framework named Qooxdoowhich is a Rich Internet Application framework based on JavaScript.we can use it tomake web desktop expediently.In the background of this desktop system.we make the system can save and processall the data of users in the cloud side by implementing the message managementmodule,user managerment module,process management module(work together withother modules). Thus,users can work in anywhere by this web desktop system.
