Web Services and More: Integrating Business Processes and Information Across Agencies

Client and Service can be front ends to existing applications

Client and Service are often front ends for existing apps/systems
- Any application/component can be exposed as a Web Service
Any granularity:
- Fine -- Not a good idea
- Course -- 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 . . .
