4. Main Points Building Service Oriented Applications can be a complex undertaking Improving frameworks and languages helps Modeling languages, tools and patterns have an important role to play We can avoid many past pitfalls

5. Agenda Complexity in connected systems Using modeling to reduce complexity Scenario 1 - web services and design for operations Scenario 2 – visualizing code Scenario 3 – implementing business processes Microsoft strategy and tools for Visual Studio 2005

6. Agenda Complexity in connected systems Using modeling to reduce complexity Scenario 1 - web services and design for operations Scenario 2 – visualizing code Scenario 3 – implementing business processes Microsoft strategy and tools for Visual Studio whidbey

7. Complexity Automate business processes Value chains with partners Customer and supplier self service Improve ROI of IT Lower operating costs Cut time to market Service oriented architecture Web Services, messaging, contractsSecurity Caching and state management Deployment policies & constraints Heterogeneous platforms Application servers & standards Schemas and databases Code and attributes Configuration files Project structures Physical server configurations ? ? New Business Requirements New Platform Technology Same Old ImplementationApproach

8. Building Software Today We still hand-stitch every application … Using low level programming constructs … Building every application as if it were the first of its kind …

9. Synthesis of Ideas Raising the level of Abstraction Modeling and domain specific languages Patterns and Frameworks Institutionalizing best practices Software Product Lines A context for systematic reuse Software component assembly Specification of contracts and software supply chains

20. Issues Concept of Web service is “lost” among many files Developer must keep files in sync Refactoring engines ignorant of Web service concepts Can not process non-code files like schemas and config files Debugging, Intellisense, editors all ignorant of Web service concepts Source Control, Work Item, Tests all ignorant of Web Service concepts

44. UML And DSLs Tools render metamodel as defined by OMG Multiple, inter-twined sub-languages, defined by committee Extended partially using stereotypes and tags Syntax and Semantics defined by OMG committee Limited range of diagram styles Based on MOF – implementations in Java Engine can render any metamodel including UML Each DSL is defined using core model and focused on specific development task Directly extended with new types and associations Syntax and Semantics defined by language users No limits, though often based on template Small core model – implementation in CLR UMLDSL Approach

45. Visual Studio 2005 Team Architect DSLs for precise development Simplify design and deployment for SOA Designing and constructing connected applications from Web services Verify application settings against logical datacenter Code Visualization UML tools for documentation and drawing

46. Need A Designer Framework For a specific domain it must … Define a metamodel for the abstractions Define a graphical notation Define how a synchronization engine should work with related artifacts Define constraints between artifacts Be extensible

47. Making Use Of Metadata Metadata collected in DSLs can be made available across the life cycle Source control systems Debuggers Testing Tools Compilers and language editors
