Top - down design and stepwise refinement urged the programmer to set forth the broad outlines of a procedure first and only later fill in the details 顶?底的设计和逐步改进的方法驱使程序员先构造一个程序的轮廓,然后再补充细节。
The paper introduced the fundamental knowledge related to the subject , studied the component and architecture , and constructed the domain component library based on the constructing process and arithmetic in the domain component library . then the arithmetic of retrieval and matching have been discussed . based on the merits of abd ( stepwise refinement ) and cbd ( building blocks method ) , it described the application combined the two kinds of theory in the practice 本文介绍了有关的理论基础,研究了构件、构架及软件体系结构,讨论了领域构件库的构建过程及算法,建立了构件库,提出了构件库中构件查询的检索及匹配方法,给出了基于构架技术的逐步细化和搭建积木方式的优点,以此为基础,进行了实际开发研究,描述了运用两者结合的理论进行开发的过程。
