RAID系统的面向对象建模

Object-Oriented Modeling for RAID Systems

廉价磁盘冗余阵列 RAID系统的使用 ,较好的解决了计算机的 I/ O瓶颈问题。由于 RAID系统本身的复杂性 ,传统的结构化分析方法已无法提供对系统全面正常的描述 ,而面向对象方法良好的封装性和重用性 ,能使系统的复杂性在一定范围内得以降低。本文以 RAID控制系统的软件设计为背景 ,采用 UML的面向对象可视化设计方法 ,从概念视图、静态视图和动态视图等多个视角 ,讨论对 RAID控制系统的建模。

The computer's I/O bottleneck is somewhat solved by Redundant Arrays of Inexpensive Disks (RAID). Due to its coherent complexity, the traditional structure analysis method can no longer provide a complete and correct description. However, the object oriented approach can help to decrease the system complexity to a certain degree with its advantage of encapsulation and reusability. In light of software design of a RAID control system, this paper discusses, from conceptual, static and dynamic views respectively, the modeling, analyzing and realization of RAID control systems using the visual, object oriented method of UML.
