3. SOA – a way of architecture
Service Oriented Architecture – generally for software.
Begs the question “What is Software Architecture?”
No single answer. Closest definition:
“A software architecture for a system is the structure or structures of the system, which consist of elements and their externally visible properties, and the relationships among them” 1
[1] “Documenting Software Architectures”, Addison Wesley, Clements et al, pp xxv, ISBN

4. What is Service Oriented Architecture (SOA)?
SOA is an Architectural Paradigm for software systems.
Marketing Pitch: SOA is a higher generalization of both ebXML and Web Services.
Roots in Object Oriented (OO) programming methodology.
Components in a state of readiness - may be “called” or “invoked”.
Modern SOA based on internet (communications) and XML (data format).
Event based in nature.
Points
Architectural paradigm and nothing more. SOA does not mean “just integration” or “just web services”

For architecture

7. Architectural Patterns
Developed by Christopher Alexander > house building.
Recognizes recurring patterns and documents them.
Important Architectural Description Language (ADL).
Not tied to any:
specific data type
programming philosophy or paradigm
programming language
methodology
“As an element in the world, each pattern is a relationship
Between a certain context, a certain system of forces
which occur repeatedly in that context, and a certain spatial
configuration which allows these forces to resolve themselves.”

11. What eb SOA is
The goal of the OASIS ebSOA Technical Committee to develop a set of blueprints and architectural patterns declaring the components and relationships between them necessary to facilitate e-business on a global basis.
A reconciliation/mapping of how technology may be employed to facilitate requirements of e-business.

12. What eb SOA is not: ebXML Web services Constraints on either
Implementable by itself
Complete (Catalog of Patterns may be added to indefinitely)
Favorable to any specific vendor
Programming language or platform-specific
