一种结合传统技术的对象分析及设计方法

对于大而复杂的应用系统,现有的面向对象的开发方法（ＯＯＤ）在识别问题域中的对象上还存在着很大困难,直接影响了需求分析的效率和质量．为此,就需要对现有的开发方法进行改造,使之能够适应开发实践的需要．笔者对当前的ＯＯＤ及功能化开发方法（ＦＤ）作了深入分析,提出了一种新型的对象分析及设计方法．该方法在ＯＯＤ原理的基础上,在对象分析中引入了ＦＤ方法,把对象细化和功能细化结合起来,在不断的细化中完成对象的识别、分析及设计．在分析完成后则采用ＯＯＤ的同态映射法,把问题域同态映射到解域．这样既能使应用系统具有良好的性质,又解决了当前ＯＯＤ在复杂问题域中对象识别难的问题．

On a New Object-oriented Analysis and Design Method

It is difficult to recognize the objects of large and complicate application systems by present object-oriented development (OOD)methods, which affects their efficiency and quality in demand analysis. For this reason, the author analyses these OOD methods and functional development(FD) method in detail, and puts forward a new object-oriented analysis and design method. In the analysis of object, FD method is introduced on the basis of OOD principle. By combining object refinement with function refinement, the recognization, analysis and design of the object are finished in continuously refining. After the analysis, the problem to be solved is homomorphously transformed from problem domain to solution domain by homomorphous mapping method. The new method can not only ensure the good nature of application systems, but also solve the problem existing in present OOD methods.
