Value of Web services technology
Open standards Web service projects are taking one-fourth the time and costing one-fifth comparable projects using traditional technology. Performance is 2 to 10 times better than expected.• HFC Bank - IFX credit card application using XML,
SOAP and XSLT• Deutsche Bank Bauspar - FixML security
transaction integration using XML messages and XSL transformations
• Hypo Vereinsbank - Integration
