After gaving some examples for modeling analysis pattern and design pattern at knowledge level using role model ,this paper presents the process for refining design pattern from role model to class model and event trace diagram of UML. In this paper,we advocate the opinion that role modeling before object modeling of UML. Through combining role model and UML ,we construct a more comprehensive modeling method for object-oriented modeling process.展开更多
