Choices
–
–
–
–
An entirely new format
XLANG (used by Microsoft)
WSFL (used by IBM, Tibco)
BPEL4WS
●
●
●
●
Business Process Execution Language for Web Services
Emerging standard
Open (a w3c standard)
Endorsed by all vendors
High Throughput
●
●
●
●
High volume of data
I/O maybe more expensive than processing
Multiple processes
Hundreds of process instances
Distributed Transactions
●
Multiple business applications
–
●
Each containing multiple datastores
A distributed transaction scheme
–
–
–
–
Coordinate a transaction between applications
Abstract commit/rollback support if available
Provide notification model
Error logging
Management
●
Configuration
–
–
–
–
●
Logging
Notification
Messaging
Data Storage/Retrieval
Monitoring
–
Per business process
●
