SALT is a native Oracle Tuxedo Web service integration solution. It reduces Oracle Tuxedo/Web service integration costs and decreases conversion processes that may exist with other solutions for accessing Oracle Tuxedo services. It enables seamless connectivity between Oracle Tuxedo applications and external Web service applications.

SALT allows existing Oracle Tuxedo services (inbound) to be easily exposed as Web services without additional programming tasks. It also allows you to create native Oracle Tuxedo applications that access external Web services (outbound) transparently.

Major Web services benefits include:

• Interoperability among distributed applications that span diverse hardware and software platforms
• Easy, widespread access to applications using Web protocols
• A cross-platform, cross-language data model (XML) that facilitates developing heterogeneous distributed applications

The following figure illustrates how the SALT gateway is used in the Oracle Tuxedo framework.
