Dependence analysis is an important approach to analyze, understand, test and maintain programs. A new kind of dependence analysis method for UML class diagrams is developed. A set of dependence relations is definedcorresponding to the relations among classes. Thus, the dependence graph of UML class diagram can be constructed from these dependence relations. Based on this model, both slicing and measurement coupling are further given as its two applications.展开更多

UML is a standard modeling language used to OO amalysis and OO design,this paper describes a method to use the UML anslysis model to analysis the application's function points. So the project manager can use it to estimate the project's size and cost in the early development.展开更多
