Oracle Enterprise Service Bus

Oracle Enterprise Service Bus (Oracle ESB), a fundamental component of Oracle's Services-Oriented Architecture suite of products, provides integration of data and enterprise applications within an organisation and their connected ( "extended" or “virtual”) enterprises.
Details.
This release of Oracle Retail Integration Bus (RIB) Essentials includes changes in architecture, technology stack, and deployment Oracle ESB is technically an 'enterprise service bus' designed and implemented in an Oracle Fusion Architecture's SOA environment; to simplify the interaction and communication between existing Oracle products, third-party applications, or any combination of these.
As a software architecture model for distributed computing it is a specialty variant of the more general client server software architecture model and promotes strictly asynchronous message oriented design for communication and interaction between applications. Its primary use is in Enterprise Application Integration of heterogeneous and complex landscapes of an organisation, and thus enabling its easy management. 
An ESB service is designed and configured with Oracle JDeveloper and Oracle ESB Control user interfaces. It is then registered to an ESB Server. The ESB Server supports multiple protocol bindings for message delivery, including HTTP/SOAP, JMS, JCA, WSIF and Java, using synchronous/asynchronous, request/reply or publish/subscribe models. Currently, the ESB Server does not support Remote Method Invocation.
Oracle Retail Integration Bus (RIB) Essentials should not be confused with Oracle Service Bus (OSB). ESB was developed by Oracle. OSB, formerly known as Aqualogic Service Bus, was acquired when Oracle bought BEA Systems. The two products are related and interchangeable.
