移动事务处理中间件的研究与设计

Research and Design of Mobile Transaction Processing Middleware

移动计算环境下,传统的事务处理中间件已不再适用,移动事务所具备的特性应设计支持移动计算环境的移动事务处理中间件.基于FM-Que移动事务模型,采用组件软件模型设计了移动事务处理中间件,此中间件达到两方面的效果:移动环境的复杂特征和变化对应用透明,移动事务应用可以类似常规应用一样进行开发;应用程序可以利用中间件方便的了解上下文环境信息,有效地实现应用相关的自适应.

Under the mobile computing environment, the mobile transaction make the traditional transaction processing middleware is no longer applicable. So the mobile transaction processing middleware for mobile computing environment should been designed. This paper proposes mobile transaction processing middleware adopted component software model design method based on the FM-Que mobile transaction model. Mobile transaction processing middleware achieve the effect of both： the complex features and changes of mobile environment is transparent for application, mobile transaction can be developed as well as traditional transaction ; application program can facilitate understanding of the context of environmental information using middleware, and can realize self-adaptive effectively.
