Inter-enterprise IS

• Share information
• Value-add industry
• Not transactional
• Integrated applications
• Government agencies, natural resource management,
  scientific communities, corporate business units

Design Constraints

• Autonomy / Loosely coupled
• Legacy systems
• Heterogenous information sources
• Information asset architecture
• Transport/message mware independent
• Distributed control

4
Basic Architecture

• Request service providers
• Query services
• Function services
• Valued added services
• Request services
• Applications
• Infrastructure services

An architectural template

• For request services and applications
• Domain-independent aspects of applications and
  value-added services
• UML views Use case, Design, Deployment
• Applied to a local government domain

6
Information architecture

• 3-tier architectures offer a domain model
  (objects) for applications
• But who owns the domain model?

Dynamic domain model specified by the application
in the declarative request

Case Study SIH

• reduce costs and improve quality of data
  available to local and state government
• streamline information sharing among councils and

Conclusion

• New styles of information system require new
  design approaches based on information
  infrastructure
• Developing workflow, wrapper kits, resource
  discovery and query planning

• Current projects include
• DSS for dryland salinity
• National Pest and Disease database
• Population Health
