Application Integration

The patterns ordered by type of coordination in EAI process and type of request:

	Application Coordinated	Transactional Coordinated	Brokered Coordinated	Process Managed (BPM) Coordinated
Information Request (IR)	Direct Connection	N/A	Aggregator	N/A
Processing Request (PR)	Direct Connection	Transactional	Broker	Managed Process

The old and new pattern names:

Old Pattern Name	New Pattern Name
Application Coordinated	Direct Connection
Transactional Coordinated	Becomes QoS
Brokered Coordinated	Broker
Process Managed (BPM) Coordinated	Split into: Serial Process Parallel Process

The Process Integration patterns have been re-engineered because:

• The distinction between R/O Information Requests and R/W Processing Requests was not found to be significant
• The distinction between Aggregator and Broker was not found to be significant
• The type of coordination was not found to be the most important characteristic by which to distinguish the patterns
• Transactionality is now defined as a QoS which can apply to any pattern
• More modern middleware provided richer process management options
• The new patterns can be applied fractally to Process Integration problems
