Technologies for E-Services : 4th International Workshop, TES 2003, Berlin, Germany, September 8, 2003, Proceedings

E-services, and in particular Web services, are emerging as a promising tech- logy for the e?ective automation of application integration across networks and organizations.

The basic technological infrastructure for e-services is structured around three major standards: SOAP, WSDL, and UDDI.

These standards p- vide building blocks for service description, discovery, and interaction.

E-service technologies have clearly in?uenced positively the development of integrated - stems by providing programmatic access to e-services through SOAP, WSDL, and UDDI.

E-services are evolving toward being able to solve critical integ- tion issues including security, transactions, collaborative processes management, semantic aspects, and seamless integration with existing middleware infrastr- tures.

VLDB-TES 2003 was the fourth workshop in a successful series of annual workshops on technologies for E-services, held in conjunction with the VLDB conference.

The objective of VLDB-TES 2003 was to bring together researchers, practitioners,anduserstoexchangenewideas,developments,andexperienceson issues related to E-services.

VLDB-TES 2003 took place in Berlin, Germany. It featured the presentation of 16 regular papers. In addition to the presentation of research papers, the workshop included two invited talks and a panel discussion.
