• Sep 2000 - IBM announces “Web services”, a new architecture

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
