SQI Remote Façade WSDL

• Common SQI WSDL Binding
• sqiFault.wsdl Fault mechanism associated with
  SQI
• sqiSessionManagement.wsdl Example of possible
  target session service
• sqiTarget.wsdl Target SQI interface
• sqiSource.wsdl Source SQI interface
• SQI Remote Façade WSDL
• Alternative to sqiTarget.wsdl
• Maps the remote façade methods

SQI Remote Façade WSDL

• Tested on MINOR
• Synchronous query mode scenario
• Reduction of 545.50 milliseconds of the overall
  query time (56.82 )
• Asynchronous query mode scenario
• Reduction of 668.73 milliseconds of the overall
  query time (70.29 )

Conclusion

• SQI remote façade
• Improves SQI performance (by minimizing the
  number of remote calls) while preserving SQI
  flexibility

• Its bindings can be deployed smoothly
• Implementation is trivial
• Backward compatibility is guaranteed

• Proposed as a starting point for a new COMMON SQI
  WSDL Binding to be discussed between all
  interested parties
