单选题 Object-oriented analysis (OOA) is a semiformal specification technique for the object-oriented paradigm. Object-oriented analysis consists of three steps. The first step is 15 . It determines how the various results are computed by the product and presents this information in the form of a 16 . and associated scenarios. The second is 17 , which determines the classes and their attributes; Then determine the interrelationships and interaction among the classes. The last step is 18 , which determines the actions performed by or to each class or subclass and presents this information in the form of 19 .

面向对象的分析(OOA)是一种面向对象范型的半形式化描述技术。面向对象的分析包括3个步骤：第一步是用例建模，它决定了如何由产品得到各项计算结果，并以用例图和相关场景的方式展现出来；第二步是类建模，它决定了类及其属性，然后确定类之间的关系和交互；最后一步是动态建模，它决定了类或每个子类的行为。并以状态图的形式进行表示。
