摘要
针对信息系统对需求变化响应不及时的问题,基于构件技术,提出敏捷信息系统的体系结构.它将系统划分为四个层次,另外,通过一条数据总线连接在一起,从根本上实现了信息系统的敏捷性,并提出一种基于体系结构的构件可靠性评估框架,可在系统运行剖面未知的情况下评估构件的可靠性.
In order to overcome the problems introduced by information system＇ s delayed response to requirements variation, based on component technology, this paper proposes an agile information system＇ s architecture. It divides the system into four layers, and joins them together by a data bus. It radically realized information system＇ s agility. This paper also proposes an architecture-based component reliability estimation frame, estimating component＇ s reliability in case, system operational profile is unknown.
