SOA Brings New Opportunities for Data Management. Presentation delivered at DAMA International Symposium, San Diego 2008.

1. SOA Brings New Opportunities to Data Management DAMA International Symposium San Diego, March 2008 Richard Veryard

4. The origins of SOA … Computing Modular programming Model-based development Object Orientation Software Components Networks Internet WWW Open Systems Open Distributed Processing Net-Centricity System-of- Systems Engineering SOA Web Services Enterprise Mash-Ups ESB & Grid Software As A Service Business Long Tail Mass Customization Business As A Platform Outsourcing Loosely Coupled Organization Enterprise Federation agility interoperability economics of scale

5. SOA Vision – Flexible, Federated Business Processes Service Service Service Service Service Payment Inventory Manufacturing Logistics Ordering Resource Resource Resource Ticket Sales Service Service Ticket Collection Service Service Service Availability federation reuse flexibility aggregation

8. from complex world … to simple schema

9. … via abstraction generalization aggregation classification

10. … via abstraction generalization aggregation classification HOTEL MOTEL ACCOMMODATION MEAL TICKET TRAVEL & SUBSISTENCE CHARGING POLICY TAXATION RULE EXPENSE ITEM

11. abstraction equals attenuation but sometimes … less reach less richness less agility less assurance

12. generalization A picture is worth a thousand words. A word is worth a thousand pictures. VEHICLE

13. different people generalize differently but sometimes … Jack and Jill … … went up the hill … … to fetch a pail of water

16. Who is right - lumper or splitter? OR AND

17. What if lumper and splitter are both right? PATIENT PERSON is-a PATIENT PERSON PERSON PATIENT TREATMENT Subtypes and Inheritance various notations PARTY

18. Decoupling Abstraction Layers PATIENT PERSON TREATMENT Splitter Model Lumper Model

19. Decoupled Services PATIENT PERSON TREATMENT Medical Services ANIMAL Other Services Other Services *

20. Decoupled Identity, Security, Privacy, Context CRIMINAL PERSON CRIME Justice Services NATIONAL THREAT Other Services Homeland Security *

21. Business Services rest on Underlying Services - e.g Identity and Context Identity Services Underlying Services Core Business Services Context Services Customer Product User-Centric Identity Identity Metasystem Identity 2.0 CardSpace Higgins YADIS SXIP

22. Identity and Identifier PERSON Business Identifier PERSON PERSONAL IDENTIFIER PASSPORT DRIVING LICENCE CREDIT CARD … *

23. User-Centric Identity Consumer Service Provider Identity Services Identity Data Business Services Consumer Service Provider Identity Services Identity Data Business Services Service Provider Business Services

24. So who is the Identity Service Provider? Consumer Service Provider Identity Services Identity Data Business Services Service Provider Business Services Credit Card Company? Telephone Company? Google Yahoo Microsoft? National / Local Government?

25. security and compliance Data as Liability Data as Asset

26. Business Services rest on Underlying Services - e.g Identity and Context Identity Services Underlying Services Core Business Services Context Services Customer Product Differentiated Service Situation Awareness

27. situation awareness Differentiated Service One-Size Fits All

30. … information gets more complex in a net-centric world … more reach more richness more agility more assurance

31. NCW Maturity Model Traditional Self-Synchronization Collaboration Organic Sources Information Sharing Shared Awareness Developing Situational Awareness Command and Control 0 1 2 3 4 source: Power to the Edge (Alberts & Hayes, DoD CCRP, 2003)

32. Example of net-centric information Supply chain visibility Materiel Distribution Information Distribution Knowledge & Intelligence 1 Historical Asset Visibility Shipment last recorded 2 Current Asset Visibility Shipment right now 3 Predictive Asset Visibility Expected arrival 4 Process Visibility Current state of process 5 Information Visibility Reliability of information 6 Knowledge Visibility Show me your reasoning Past Shipment Present Shipment Future Shipment 1 2 3 4 5 6

33. Another key semantic question … HOW MANY? BANK “ Jack and Jill have a joint checking account, so we regard them as a single instance of CUSTOMER.” HOSPITAL “ Every time Jack is admitted to hospital, we start a new patient record.” LIBRARY “ When Jill was a student, she had a student card. Now she is a member of staff, she is registered through a completely different system.”

35. Different Use of Same System / Service Legacy System Sales Prospect Prospect’s secretary Sales Exec 1 Sales Prospect and secretary is another Sales Prospect Sales Exec 2 Sales Prospect System Designer

36. Semantic Alignment Heterogeneous Service Composition Composition mySAP Wrapped Legacy Mashup eBay SalesForce GoogleMap

37. Semantic Generalization CUSTOMER Identity Rule CUSTOMER IDENTITY POLICY Membership Rule MEMBERSHIP POLICY

40. ≈ knowledge ≈ data ≈ information Location Route Shipment Core Business Services Planning Deployment Distribution Problem-Solving Process Services Automated Reasoning Capability Manifesting Service ERP capability Routing and Rating Service Capability Services Identity & Security Services Geospatial Services Collaboration Services Utility Services COTS Underlying Services Text file Database Portal Warehouse Data Mart Heterogeneous Data Sources Metadata Repository Registry Metadata Storage Translation & Mapping Services Text access Database access Portal access Warehouse access Data Mart access Data Integration Services

41. Understanding Business Semantics Business Semantic Model Business Type Model Business Information Needs Resource-Based Services Information Schemas Document & Message Schemas Interface & Storage Schemas Enquiry-Based Services Services Business Capability Model

42. Semantic Modeling feeds Service Planning Company Accounts and other documents Business Concept Model Business Type Model Customer Relationship <<concept>> Customer <<type>> Semantic Modeling Business Semantics Service View (for a Domain) Customers Service <<service>> <<domain>> Customer Management Business Domain Definitions Identify (Core Business) Services & Dependencies high-level model detailed domain model Identify Business Domains Service Portfolio Planning

43. How does EA accommodate SOA? WHAT HOW WHERE WHO WHEN WHY FOR WHOM? Zachman TOGAF DODAF MODAF Single Business System Model (Logical) Service Interoperability Single Service Business Collaboration Enterprise Model (Conceptual)
