Combing the advantages of mda , this thesis put forward a component development method , that is mdac ( mda - based component development ) . the main idea of mdac is that developing , implementing , compositing , and reusing components by modeling , model transformation , model integration , and model reuse . the main work of this thesis as follows : ( 1 ) study the framework , related concepts , key technologies , and the importance of mda 本文在深入研究mda架构的基础上，通过使用mda的优点来弥补当前构件技术的不足，提出了一种系统的、全面的基于mda的构件开发方法? ? mdac方法，其主要思想是融合模型驱动和构件的思想到软件开发生命周期的各个阶段，利用模型来开发构件，化构件开发为模型开发，化构件组装为模型组装，化构件实现为模型映射，化构件复用为高层设计的复用、模型的复用。
The same time , the writer deeply researches and analyzes the software risk management model , software risk management tools and methods , risk management implementation , the attribute of different phases in the software development life - cycle and combines with successful experience of managing the risk met in the work 与此同时，笔者对软件风险管理研究领域中的代表人物bohem等有关软件风险管理模式、软件风险管理工具和方法、软件风险管理实施、以及软件开发生命周期各个阶段的特征等文献进行了深入研究，并且结合了实际工作中的成功经验。
Testing has its own lifecycle that parallels the design and development lifecycle - test planning , requirements analysis , design of test cases , writing of test cases , test execution and traceability - and can only be managed effectively when the right level of resources are dedicated to it 测试拥有与设计和开发生命周期并行的其自身的生命周期-测试计划、需求分析、测试实例设计、撰写测试实例、测试执行和可追踪性-并且只能在有适当级别的资源时才能被有效管理。
