【摘要】 在软件工程研究的历程中，诞生了许多方法，其中以面向功能的结构化方法和面向对象方法最为著名和被广泛应用。面向对象的思想非常适合构造复杂的软件系统，面向对象的软件开发方法为大规模复杂系统的开发提供了有效手段。统一建模语言UML是面向对象领域中的重要结果，可用于描述、视化和构架软件系统，它融合了Booch、OMT和OOSE方法中的概念，集中在设计通用的元模型上(统一不同方法的语义)和建立通用的表示法(提供对这些语义的形象化的表达)，它是为使用者广泛采用的建模语言，适用于各种软件开发方法、软件生命周期的各个阶段、各种应用领域以及各种开发工具。利用UML能有效控制复杂性、适应多变性，具有灵活性、低风险性、可重用性，从而能提高系统开发效率。 本论文在对UML建模语言的研究基础上，对航空数据链数传系统软件进行了建模实践，最终描述了一个可视化的模拟数传系统。论文首先介绍了统一建模语言UML的定义、特点及应用情况，并分析了该语言的优缺点，接着介绍了基于UML的建模过程特点和本课题的建模过程，最后对数传系统进行详细的建模工作，并给出部分模型。其中，对具体的建模过程进行了详细的阐述。更多还原

【Abstract】 There are many methods in the course of studying software engineering. In these methods, Structured Method and Object-Oriented Method are most famous and they are used broadly. Object-Oriented idea is very fit to construct complex software system, Object-Oriented software development approach is an effective approach for large-scale complex systems. UML ( Unified Modeling Language ) is one of the latest achievements in software engineering field. It can be used in specifying, visualizing and constructing the software systems. The Unified Modeling Language fuses the concepts of Booch, OMT and OOSE. It concentrates first on a common metamodel ( which unifies semantics ) and second on a common notation ( which provides a human rendering of these semantics ). UML is a common modeling language, it applys to all kinds of software development methods, every stage of software life cycle, all fields and many tools. So we can control system complexity efficiently, the system has changeability, flexibility, low venture and it can be reused again. Thus the development efficiency can be improved greatly.The thesis models the data transmission system in aviation data links based on the study of Unified Modeling Language, a visual simulate system is specified in the end. First the thesis introduces the definition, analyses the characteristics and applications. Second, it provides the characteristics of modeling process and specifies the process of data transmission system. Last, the part-model of the system is presented.更多还原
