Tian Zhang @ Nanjing University 3 Part I „ OMG's technology adoption process „ UML 1.4, 1.5, 2.0 „ UML 2.0 in MDA „ The current status of UML 2.0

OMG's Technology Adoption Process 1.( Optional RFI stage OMG在1999年提出UML的修订信息需求 来自不同领域的26个响应者大多数提议进行重大修订 2.TF issues RFP,evaluates submissions OMG于2000年初发布UML2.0的四部分提案需求 3. Voting to Adopt an OMG specification 4. Finalization getting ready for prime time 今年1O月通过了Superstructure的最终正式版 其余部分仍处于最终修改版阶段 5. The OMG specification maintenance Cycle 6. Retiring Obsolete Specifications Tian Zhang Nanjing University

UML 2.0 RFPs Superstructure Diagram Interchange Defines user-level constructs to specify structure and behavior of systems(e.g.,class diagrams,sequence diagrams) Infrastructure OCL Defines basic constructs to specify UML and to customize it for specific domains (e.g.,real-time) Tian Zhang Nanjing University 5

UML2.0 Infrastructure设计目标 ·定义一个元语言的核心-基础结构库(Infra- structureLibrary)通过对此核心的复用，除了 可以定义一个自展的UML元模型之外，还可以 定义其他元模型，包括MOF和CWM; ■通过共用核心包，UML和MOF、CWM在体系 结构上保持一致。 Tian Zhang Nanjing University

Goals of UML 2.0 Superstructure Restructure and refine the language to make it easier to apply, implement and customize Improve support for component-based development specify both platform-independent components (e.g.,business components)and platform-specific components (e.g.,EJB,COM+) Refine architectural specification capabilities ▣ support hierarchical composition of parts with interfaces (compare SDL blocks and processes) Increase the scalability,precision and integration of behavioral diagrams augment sequence diagrams with advanced constructs from MSCs that can be combined and integrated with other behavior update state machines diagrams to make generalizable and able to support a transition-centric view revise activity diagrams to support more flexible parallelism and furnish more 1/O options 口 support executable models Review all UML 1.x constructs and diagrams Tian Zhang Nanjing University

UML2.0 Superstructure设计日标 ■严格地复用Infrastructure中的模型构造物 既可以描述平台无关构件（如业务构件），也可以描 述平台相关构件（如EJB,COM+等），提高对基于 构件开发和MDA的支持； 支持接口、部件和连接子，及其层次化组合能力，从 而提高对架构的规约能力； ■增强行为图的可伸缩性、精确性和集成能力； 支持可执行模型： 审定所有UML1x的构造物和图，适当地精化、取缔 和逐步淘汰。 Tian Zhang Nanjing University 8
