问题 Traditional structured analysis techniques focus upon the flow of(71)within a system. Object - oriented analysis emphasizes the building of real - world models. It examines requirements from the perspective of the classes and objects found in the vocabulary of the(72)domain.
   Traditional system design method emphasizes the proper and effective structure of a complex system. Object -oriented design method encompasses the process of object -oriented decomposition and a(73)for depicting both logical and physical as well as static and dynamic models of the system under design.
   Object - oriented programming is a method of implementation in which programs are organized as cooperative collections of objects, each of which represents an(74)of some class, and whose classes are all members of a hierarchy of classes united via(75)relationships.

选项 A、control
B、inheritance
C、inference
D、connection

答案B

解析 (参考译文)传统的结构化分析技术关注系统内部数据的流动。面向对象分析方法强调建立现实世界的模型。面向对象分析方法从问题域中的类与对对象的角度考查需求。
   传统的系统设计方法强调正确有效的分析复杂系统的结构。面向对象的设计方法强调面向对象的结构过程,强调描述所设计系统中的逻辑的、物理的、静态的、动态的模型。
   面向对象的程序设计是一种系统实施方法,在这种方法中,程序是通过互相合作的对象集合组织起来的,其中每个对象都是有某些类的一个实例,而这些类又都是通过继承关系构建起来的类等级体系的成员。
