基于UML的面向对象建模方法及其在血站管理系统中的应用研究-计算机软件与理论专业论文.docx

Abstract ηle ObjectOriented Modeling is an important direction for the research in software developmen t. UML is a well-defined ，easy expressed ，strong function Object-Oriented Modeling language;ηle ObjectOriented Modeling technique based on UML is applied increasingly in so仕ware development. However，UML is only a sort of modeling language，not a sort of modeling methodology. 丁he models fmally build the frameworks of the system. Its difficult to test system through executing these models and to ensure the coherence between these models. We need a modeling environment witch can finally build executable models and ensure the coherence between these models. In this thesis，we do much research on ObjectOriented Modeling Method based on UML，and extend the modeling environment ，and finally applied to a blood station management system for Nanjing Red Cross Blood Center. Firstly，this 出esis improved the modeling method based on UML through introducing CFG to UML modeling environment，witch made the models executable; Secondly，the thesis proposed a novel method to improve the traditional UML modeling environments through importing OPD witch can avoid consistency questions among UML multi-models efficiently. 白lirdly，we described the way transfonning from UML model into code and analysed MSF. We also proposed a proto印pe of code generat侃Last1y，the thesis applies the UML modeling method to a blood station management system for Na时ing Red Cross B100d Center， and vaHdated the methods proposed in thís thesís. It is indicated in practice that introducing CFG and OPD to UML based modeling environment is very convenient for system requirement analysis; over划1 design and detail design and can greatly improve the efficiency and shorten the software development course.
