4. Case Study: Procure to Pay Process Customer Division Shared Service Supplier Outsourced But … Technology Applied Correctly can Pave the Way for successful Business Innovation • Standards (including open source) for interoperability • Self-defined, loosely coupled interfaces • Tools to visualize and integrate existing assets • Model Driven Architecture (MDA) • Service Oriented Architecture (SOA) • Business Innovation & Optimization

Das ist eine IDOC “.NET. I like it.” “Those lying IMS swine. Those arestored procedures.” |Printed on 2005-4-18

6. What is Service-Oriented Architecture (SOA) ? SOA is different things to different people: • a set of services that a business wants to expose to their customers and partners, or other portions of the organization • an architectural style which requires a service provider, requestor and a service description • a set of architectural principles, patterns and criteria which address characteristics such as modularity, encapsulation, loose coupling, separation of concerns, reuse, composability • a programming model complete with standards, tools and technologies such as Web Services • A set of standards Business Executive, Consultant Architect Developer

7. SOA Defining Concepts Universal Connectivity: Integrates most diverse environments, bridging protocols, languages, platforms, APIs and messaging paradigms – providing scale and scope of integration required by today’s extended enterprise Incremental Integration: Start small and plug in capability to enrich your implementation as needs dictate Service Orientation: Facilitates loose coupling between software components Flexibility: A variety of options for persistence, reliability, security, availability... Deploy where required, manage centrally Event Orientation: Decouples applications that publish business events from subscribing applications Open, standards-based: Open APIs and protocols support the interoperability and substitution of middleware from multiple vendors

8. What’s Different about Web Services? • Haven’t we heard this before? • Structured programming and modules? • Message Passing/Driven Systems? • Remote Procedure Calls? • OO Languages? • CORBA, Distributed Smalltalk • J2EE • This time we really mean it. No kidding. • If you can’t take a joke, you shouldn’t be using distributed systems. • There are some differences • Microsoft supports this model • XML is more language and implementation agnostic. • WSDL, WS-Interop include RPC and Messaging from day one;One is not added to the other. • XML and WSDL is more forgiving of change in messages and evolution of interfaces. • Common model for “services/impls,” “data in DB,” “data in flight.”

10. Daddy,Mommy gave me thesedocuments to convert. What type of EJB do you want to build? Um. I do not want to build an EJB. You see, Mommy gave me these … Maybe you didn’t understand the question.Your choices are SLSB, SFSB, CMP Entity, BMP Entity, MDB You’re not very nice. Simplifying Development • This is crazy. • Programmers want to build a “part” that implements a “basic building block” and then aggregate them together

17. IBM and OMG Standards Influence– Representative Samples • Long standing member since the earliest days of OMG • OMG Board of Directors, Architecture Board, Task Force Chairs • Led the specification and implementation of several key standards (* work in progress) • Modeling – UML 1.x, UML 2.x and various profiles • Metadata – MOF 1.x, MOF 2.x, XMI and various metamodels • Software Reuse and Asset Management - RAS 2.0 • Data Warehousing – CWM 1.0 • Legacy Integration/Re-engineering – KDM* • Business Modeling (BPDM*) and Business Rules (BSBR*, PRR*) • Ontology (ODM*) • Middleware Interoperability – CORBA IIOP (J2EE™) • Domain Standards (LSID – Life Sciences…) • Focus : Integration of Modeling and SOA Standards IBM Products : Tools Integration & Metadata – Eclipse and EMF, Modeling RSA

19. Pattern describes a solution to a recurring problem for a context realized as Automation RUP / GS Method Configurable Component/Service/RSA Transform, Pattern/Template/ … Guidance references recognizes & documents uses creates (later) customizes an asset + The codified pattern may be further customized by less skilled users. Implementing Patterns • Patterns may be implemented as process guidance or may be codified within tooling The solution described by a pattern may be implemented in a component, or across several components, or in a service. There are various codifications of patterns. • Configurable Component: parameterized software component implementing one or more patterns; may be published as a service • RSA Transform, Pattern: implements a pattern through actions which modify model elements and other artifacts • Template: contains sections marked for substitution with parameters supplied by the user RSA – Rational Software Architect

20. Rational Software Architect: Patterns Pattern rendered as a collaboration to support incremental application • “Pattern-apply” experience is highly interactive • Evolution of previous generations of pattern mechanism experiences • “Pattern-authoring” experience provides flexibility using Open API • GOF design pattern content • Additional patterns provided via RAS repository on developerWorks • Examples: SOA / Web Service design patterns, J2EE patterns etc • Pragmatic example of applying MDA Transformations • Example : Enterprise Patterns on Developerworks Support “drag-and-drop” of pattern parameters into the collaboration • Impact: • Leverage existing skills and assets • Basis for asset-based development practice New patterns view providing outline and description of the pattern

21. Business Modeling Landscape Simulation simulator "overlays" statistical distributions Governance strategic goals, policies, capabilities Observation events, metrics, KPIs, business situations • Business Process Definition Metamodel (BPDM) • Web Services Business Process Execution Language (WSBPEL) • Business Process Modeling Notation (BPMN) Rules Business rules Authorization permissions and prohibitions • Business Rules (BSBR, PRR, BRM) Process business tasks User Interaction user interfaces, dashboards Services service providers and service interfaces Resource resources and roles Information business artifacts Organization hierarchical structures organizations, locations

22. Summary • SOA and MDA are mutually reinforcing. • OMG compliments W3C and OASIS • W3C and OASIS focus on SOA interoperability • WS-* protocols and formats • WSDL and WS-Policy for interface definition and tool interoperability • OMG defines the “tool flows” • Modeling (UML) • Rules • Meta-models; Processes • Legacy Modernization • Domains/Verticals • Challenges • Domain/Vertical support in “SOA” • Need to improve the “mapping” between SOA and UML • Modeling IT infrastructure, Security, etc. • End-to-End Policy and Rules • Seamless hand-off from development tools to systems management products • Application development  IT Management “meta-model and process”
