Software Engineering 1. History of Object Oriented Method

上大学1.1 The Growth of OO Methods SHANGHAI JIAO TONG UNIVERSITY In 1965 the first object-oriented (OO)programming language,Simula l,was introduced. Almost immediately interest in OO design began to rapidly grow. This led to the emergence of numerous competing OO design methods. Software Engineering

上浒充通大学 SHANGHAI JIAO TONG UNIVERSITY OO Analysis vs.OO Design Analysis refers to understanding the problem. Design refers to coming up with the solution. Don't confuse with broader use of word “design” Software Engineering
