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

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

The Service-Based Business (SBB)
Strategic Focus
Edge of the organization
Identification and delivery of added-value to customers.
Identification and consumption of added value from suppliers.
Operational Focus
Understanding the organization as a network of services.
Managing IT support via SOA.
Internal transformation.

from complex world … to simple schema

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

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

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

“ lumpers” see similarities
Jack fell down and broke his crown …
… and Jill came tumbling after.
“ Jack and Jill are essentially the same, and belong to the same type.”

“ splitters” focus on differences
Jack fell down and broke his crown …
… and Jill came tumbling after.
“ There are important differences between Jack and Jill, so they belong to different types.”

Who is right - lumper or splitter? OR AND

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

Decoupling Abstraction Layers PATIENT PERSON TREATMENT Splitter Model Lumper Model

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

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

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

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

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

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?

security and compliance Data as Liability Data as Asset

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

Decoupling WHAT from HOW

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

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)

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

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.”

How many books?
Identity Rule
Does the paperback version count as a separate instance of BOOK?
Membership Rule
Does the audio version count as a BOOK?

Making the Data Model more flexible
Weaker Model
Broad inclusive concepts
Broad time horizon
Weak constraints
optional
many
transferable
Stronger Model
Narrow exclusive concepts
Narrow time horizon
Strong constraints
mandatory

fixed
From the Strong to the Weak Post Before Processing

Semantic Precision
Semantic Modeling
Need semantic clarity and precision - especially membership and identity
Designers often fail to anticipate the full semantic experience
Users often find ways of informally enriching the semantics
What’s New For SOA
At the logical level, the semantic issues are much the same as for pre-SOA
But the emphasis has changed.
The biggest interoperability risks are at the semantic level.
Therefore semantic precision is a critical success factor for the achievement of SOA goals.

What data architects need to do to accommodate SOA …
Architectural Modeling
Develop high-level business type model
Recovery, consolidation and reengineering of existing data architectures & models
Develop detailed business type models
Architectural Framework
Establish Reference Architecture for Data
Identify data architecture deliverables - levels, level of detail, for each stage
Architectural Governance
Establish Data Policy
Exert Architectural Control
Service Planning
Support Domain Identification
Data Triage
Asset Strategy
Review third-party data architectures and industry models
Determine data architecture strategy for external models
MetaData Strategy
Establish metadata repository linkage
Use metadata to drive service factory

SOA Meta Model Report
Creating a UML Profile from the CBDI SAE Meta Model
CBDI, with assistance from our members, has put a tremendous amount of effort into the creation of a meta model for SOA and has received very positive feedback. We are frequently asked how to actually use it in the course of day to day service planning and provisioning. This article lays out a UML profile that maps the SAE Meta Model to UML and may be used as the basis for capturing a complete set of SAE models in a standard UML tool.
Product Report
Salamander’s MooD - Modeling Business Driven SOA
The Salamander Organization have recently introduced SOA modeling capabilities to their MooD Business Architect toolset, supporting the CBDI Forum’s SAE Meta Model for SOA. In this report we look at how MooD delivers convergence of both business and Service architecture modeling, and examine the coverage it provides for the meta model.

Case Studies
There is a significant demand for SOA case studies, from would-be adopters and practitioners of SOA. There is also a considerable supply of SOA case studies, mostly from vendors. But I don't see the supply meeting the demand …
