Service-oriented architecture is one of the most widely accepted architectural approaches to building and integrating applications. Oracle Tuxedo is one of the original SOA platforms. Everything in Tuxedo is a service and invoked as a service. Tuxedo services are location and implementation-independent, adhere to a contract, and are interoperable with other Tuxedo services and other service-oriented platforms. As a result, integrating Tuxedo applications into a SOA environment is natural and straightforward. This white paper covers the various integration techniques that can be utilized to integrate Tuxedo applications into a SOA world.
