2. Enterprise Application Integration
Modern enterprises use a number of systems

3. Enterprise Application Integration
Customers don't care about systems... they
expect service to be delivered.

4. Enterprise Application Integration
Integration is the solution

5. Enterprise Application Integration
EAI seeks to provide efficient, reliable and
secure data exchange between multiple
enterprise applications

6. Enterprise Application Integration
Types of integration:
● Information portals
● Data replication
● Shared business functions
● Service-oriented architecture
● Distributed business processes
● Business-to-business integration

7. Enterprise Application Integration
Fundamental challenges:
● Networks are unreliable
● Networks are slow
● Any two applications are different
● Change is inevitable

8. Enterprise Application Integration
Main integration approaches:
● File Transfer
● Shared Database
● Remote Procedure Invocation
● Messaging

10. Enterprise Application Integration
File Transfer:
● simplest form of integration
● suitable for infrequent updates

11. Enterprise Application Integration
Shared Database:
● fast data exchange
● requires strict team cooperation

12. Enterprise Application Integration
Remote Procedure Invocation:
● applies the principle of encapsulation by
hiding data to maintain their integrity
● Web Services using standards as SOAP

13. Enterprise Application Integration
Messaging:
● high-speed
● asynchronous
● reliable

16. Enterprise Application Integration
Why use Messaging:
● it is more immediate than File Transfer
● better encapsulated than Shared Database
● more reliable than Remote Procedure Call

17. Enterprise Application Integration
Specific benefits:
● remote communication between separate
applications
● send-and-forget communication
● store-and-forward

18. Enterprise Application Integration
Challenges:
● Complex programming model
● Sequence issues
● Synchronous scenarios
● Performance
