基于任务模型的移动服务可视化设计

移动通信技术及移动设备的发展和普及刺激了人们对基于Web的移动服务的需求。移动服务的特点要求服务可视化设计工具改变以往以页面为中心的设计模式，强调任务流程的设计。把任务模型应用到一个实现工具中，需要考虑很多实现细节问题，否则设计产生的应用将是不完整的。本文介绍了一个基于任务的移动服务可视化设计工具VMSDT，通过建立动作模型和任务模型来支持完整的任务流程的设计，并通过对三层架构模型中服务处理逻辑的分析，保证所创建的服务是完整的。

Visual Design of Mobile Service Based on Task Model

With the development of mobile communication technology and the popularization of mobile device,the requirement for mobile based on Web service has greatly increased. However,the characteristics of mobile service propose new demands for the visual service development tools. It requires that the tools should change the current design pattern from page-centric to task-centric. When we apply task model to an implementing tool,many detail problems should be considered,or the result of design will not be integral. This paper introduces a visual development tool named VMSDT for mobile service which supports the design of task process. In order to guarantee the integrity of the service,this paper analyzes the process logic of the three-tier computing model.
