Integrating Business Processes

Client with back-end app; Web service with back-end app

Client and Service are often front ends for existing apps/systems
- Any application/component can be exposed as a Web Service
Any granularity

Coarse -- Best value

Allows clean integration across:
- Departments, agencies, companies, etc.
Loose coupling
- Client and Service can use different platforms and programming languages
- Only need to agree on interface
One Web Service can make use of others . . .
