上游充通大兽 Object Design SHANGHAI JIAO TONG UNIVERSITY Object design is the process of adding details to the requirements analysis and making implementation decisions The object designer must choose among different ways to implement the analysis model with the goal to minimize execution time,memory and other measures of cost. Requirements Analysis:The functional model and the dynamic model deliver operations for the object model Object Design:We decide on where to put these operations in the object model Object design serves as the basis of implementation Software Engineering
