  2. MOF Profiles OCL StateMachines StructuredClasses andComponents Activities Interactions DetailedActions Flows Basic UML(Classes, Basic behavior, Internal structure, Use cases…) UML Infrastructure UML Overview • Visual modeling language • Providing controllable levels of abstraction • Definition of static and dynamic model features • Communicating/predicting application design characteristics in domain-terms • Supporting automation of development process • Derived from OMT, Use Case and Booch (Component) methodologies • Dominant modeling language for software architecture “blueprints” Credit Bran Selic, “An Overview of Model-Driven Development and UML 2.0”

  3. A B Richer Language Features • Architectural modeling: composition and stronger encapsulation via structured classes • Components model internal structure, required interfaces and support deployment • Ports connect class interfaces toenvironment • Protocol definable on connection • Data or control flow • Deeper profile extension mechanism (than stereotypes, tags and constraints) with UML meta-model extensions • P latform-specific terminology, UML symbols and semantics • Full integration with MOF providing tool integration

  4. sd ATM-transaction client: atm: dbase: insertCard ref CheckPin alt [chk= OK] ref DoTransaction error(badPIN) [else] Enhanced Behavioral Modeling Capture Problems at Model Level • Extended sequence diagrams permit more detailed complex interactions • Supports sub-diagrams • Decomposition of SDL, MSC and LSC messages • Control structures: loop, parallel execution, alternative execution,protected regions, ... • Activities permit more flexible parallelism, I/O options and data/control flow modeling • Petri Net model to derive concurrency • Unstructured activities possible • Pre/post conditions • HPEC features described in HPEC 2001 e.g. interruptible regions and executionordering

  5. sd DriverProtocol d : Driver Idle Wait Busy Idle o : OutPin 0111 0111 0011 0001 t = 0 t = 5 t = 10 t = 15 Timing and State Modeling • Precise modeling of timing via timing sub-diagrams • Previous profile for modeling schedulability, performance and time embedded in UML 2.0 • Enables next level of integrating hardware modeling to platform design • Statecharts now have sub-statecharts and inheritance

  6. UML 2.0 Provides HPEC “Potential” for Software Design Automation • Action semantics integrate activities with related low-level actions • There are many methods of UML-based code generation • State translation (I-Logix, Rose RT) • Formal translation (NU research, Telelogix) • Direct template translation (Pathfinder) • MDA-based model execution (Pathfinder, Component-X, 88solutions) • Generate/discover components (PCA) • Low-level data/state flow import (MathWorks) • Informal indirect translation to non-mainstream tools and PGO (HPEC 2000) • Model Integrated Computing (MIC, MOBIES)
