Object-oriented analysis (OOA) is a semiformal specification technique for the object-oriented paradigm. Object-oriented analysis consists ofthree steps. The first step is (6) . It determines how the various results are computed by the product and presents this information in the form of a (7) and associated scenarios. The second is (8) , which determines the classes and their attributes, then determines the interrelationships and interaction among the classes. The last step is (9) , which determines the actions performed by or to each class or subclass and presents this information in the form of (10) .

A．use-casemodeling

B．classmodeling

C．dynamicmodeling

D．behavioralmodeling
