【Abstract】 This paper proposes an application framework meta-model based on UML (unified modeling language) notation from the perspective of construction and composition of application frameworks, gives the semantic of framework elements, and specially discusses the hot-spots description methods and their implementation mechanisms. Finally, the paper presents an example of the application framework meta-model, i.e., the telecommunication integrated business system framework, and proposes a reuse method of the application framework.更多还原
