SOA is an
architecture style
that creates
reusable network
accessible,
interoperable
services, using
vendor neutral
standards
Business Processes
Process Composition

SOA Features
 SOA is for Composite Business Applications
 SOA is a movement from monolithic to matrix
 Reuse and Remix are the key recipes and all other characteristics support this in
some form or fashion
 Black-box component architecture hiding complexity wherever possible
SOA Characteristics
 Reusable




Abstracted
Published
Loose Coupling
Business Process focus
Web Services – Technology that Powers SOA
Web services are self-contained and self-describing software components that
expose application functionality that can be processed through open internet
standards

Broker
UDDI
WSDL
WSDL
SOAP
Service
Requester
Service
Provider

Based on loosely coupled architecture, which
increases adaptability to changing requirements

Independent of the implementation language and
environment

Use widely known and accepted web standards:

WSDL – Web Services Definition Language

SOAP – Simple Object Access Protocol

UDDI – Universal Description, Discovery and
Integration
Web Services Standards

SOAP is a simple XML-based protocol to let applications exchange
information over HTTP.

SOAP stands for Simple Object Access Protocol
 SOAP is designed to communicate via Internet
 SOAP is platform independent and is a W3C Standard

WSDL is an XML-based language for describing Web services and how
to access them.

WSDL stands for Web Services Description Language
 Captures the “Service contract” between the service provider and consumer
– What operations does the service contain
– How to invoke the operations (what url?)
– What data to send and what to expect in return
 W3C Standard
 UDDI is an XML based language for registering and discovering services

UDDI powers service reuse

Web Dynpro
 Uses MVC pattern
 2 Flavors – ABAP and Java
 Very rich component model
Visual Composer
 Web based visual modeling
tool
 Rapid code free development
of customizable portal
applications by BPX
 Mostly favored for analytics
and use by BPX for simple
needs
Adobe Interactive Forms
 Paper form look and feel
 Can be populated with
context specific data (e.g.
based on user role)
 Capable of offline processing
