Leveraging Web Services in an SOA

ABSTRACT:

This white paper examines features of the EMC® Documentum® platform that enables its industry-leading enterprise content management capabilities to participate in a service oriented architecture (SOA) and communicate with other systems via web services. The primary enabling features, EMC Documentum Foundation Services (DFS), is examined in technical detail, and sample code fragments that illustrate how to use DFS are provided. The EMC Documentum Process Suite is also examined as a prototypical orchestrator of SOA services. After reading this paper, you should have a good understanding of how to access services in an SOA using Web services.

Next-Generation SOA Infrastructure

ABSTRACT:

This white paper discusses the most important industry standards that are becoming available for developers to build interoperable services and composite applications, including JAX-WS, BPEL, WS-ReliableMessaging, WS-Addressing, SOAP with Attachments, MTOM, WS-Policy, UDDI, WS-Security and Service Component Architecture. Oracle has helped to define these standards and is using them as the basic building blocks for the Fusion Middleware platform. Because the Oracle platform is built from the ground up on standards, developers can create portable and interoperable services that are guaranteed to work together. And because Oracle's SOA environment is based on a common service infrastructure that is shared across the entire Oracle Fusion Middleware product, developers benefit from out of the box integration with the full range of Oracle SOA technologies, including BPEL, Human Workflow, ESB, and Oracle Rules.

What is SOA?

Service Oriented Architecture is an architectural paradigm and discipline that may be used to build infrastructures enabling those with needs (consumers) and those with capabilities (providers) to interact via services across disparate domains of technology and ownership. Services act as the core facilitator of electronic data interchanges yet require additional mechanisms
in order to function. Several new trends in the computer industry rely upon SOA as the enabling foundation. These include the automation of Business Process Management (BPM), composite applications (applications that aggregate multiple services to function), and the multitude of new architecture and design patterns generally referred to as Web 2.0.
