【摘要】 面向对象的开发方法是一种很有前途的软件开发方法．它通过对应用系统的问题空间对象直接建模，然后将它们同态映射到解空间，使应用易理解、易维护．然而，对于大而复杂的应用系统，这种方法较难识别问题空间中的对象．本文在比较了功能化和面向对象的开发这两种方法后，提出了一种基于细化的对象分析和设计方法ＲＯＡＤ．更多还原

【Abstract】 Object-oriented development is a promising method for software development. It models problem space objects directly, then isomorphically maps the problem space onto the corresponding solution space. However, it is difficult to find problem space objects for a pure OOD method. In this paper, after comparing object-oriented development with functional development, a method called ROAD, refinement -based object analysis and design, is proposed.更多还原
