Oracle SOA Suite puts a strong emphasis on standards and interoperability. Among the standards it leverages are:

• Service Component Architecture (SCA) assembly model

  Provides the service details and their interdependencies to form composite applications. SCA enables you to represent business logic as reusable service components that can be easily integrated into any SCA-compliant application. The resulting application is known as a SOA composite application. The specification for the SCA standard is maintained by the Organization for the Advancement of Structured Information Standards (OASIS) through the Open Composite Services Architecture (CSA) Member Section:

• Service Data Objects (SDO)

  Specifies a standard data method and can modify business data regardless of how it is physically accessed. Knowledge is not required about how to access a particular back-end data source to use SDO in a SOA composite application. Consequently, you can use static or dynamic programming styles and obtain connected and disconnected access.

• Business Process Execution Language (BPEL)

  Provides enterprises with an industry standard for business-process orchestration and execution. Using BPEL, you design a business process that integrates a series of discrete services into an end-to-end process flow. This integration reduces process cost and complexity. BPEL versions 1.1 and 2.0 are supported.

• XSL Transformations (XSLT)

  Processes XML documents and transforms document data from one XML schema to another.

• XQuery Transformations (XQuery)

  Queries and transforms collections of structured and unstructured data, typically in the form of XML.

• Java Connector Architecture (JCA)

  Provides a Java technology solution to the problem of connectivity between the many application servers in Enterprise Information Systems (EIS).

• Java Messaging Service (JMS)

  Provides a messaging standard that allows application components based on the Java 2 Platform, Enterprise Edition (Java EE) to access business logic distributed among heterogeneous systems.

• Web Service Definition Language (WSDL) file

  Provides the entry points into a SOA composite application. The WSDL file provides a standard contract language and is central for understanding the capabilities of a service.

• Simple Object Access Protocol (SOAP)

  Provides the default network protocol for message delivery.

• Representational State Transfer (REST)

  Provides an architecture for designing network applications. RESTful applications use HTTP requests to post data (create and update), get data (for example, make queries), and delete data. REST provides an alternative to using web services.

• JavaScript Object Notation (JSON)

  Provides a language for representing simple data structures and associative arrays called objects. JSON is a standard designed for human-readable data interchange. JSON is derived from the JavaScript scripting language.

• Web Application Description Language (WADL)

  Provides a readable XML description of HTTP-based web applications (typically REST web services). WADL simplifies the reuse of web services based on the existing HTTP architecture of the web.
