Service-oriented architecture - Wikipedia, the free encyclopedia Service oriented architecture relies on the ability to identify services and their capabilities. In computing, the term Service-Oriented Architecture (SOA) expresses a perspective of software architecture that defines the use of services to support the requirements of software users. The modeling and design methodology for SOA applications has become known by the terms service-oriented analysis and design and SODA. en.wikipedia.org /wiki/Service-oriented_architecture   (1708 words)

What is service-oriented architecture? As the latest evolution of software, service-oriented architecture (SOA) has been a hot topic for sometime now. ervice-oriented architecture (SOA) is an evolution of distributed computing based on the request/reply design paradigm for synchronous and asynchronous applications. SOA enables upgrading individual services or services consumers; it is not necessary to completely rewrite an application or keep an existing system that no longer addresses the new business requirements. www.javaworld.com /javaworld/jw-06-2005/jw-0613-soa.html   (1771 words)

Cover Pages: Service Oriented Architecture (SOA) For the purposes of this paper, SOA is defined by abstracting the common concepts and elements from architectures and standards that claim to be service oriented. Service Oriented Architecture (SOA) is an evolution of the Component Based Architecture, Interface Based Design (Object Oriented) and Distributed Systems of the 1990s, such as DCOM, CORBA, J2EE, and the Internet in general. SOA does not have a standardized, reference model yet; however, implementations share the main concepts of services, service descriptions, advertising and discovery, the specification of an associated data model, and the use of a service contract. xml.coverpages.org /soa.html   (5881 words)

webservices.xml.com: What Is Service-Oriented Architecture SOA leverages the use of web services as a means of communicating with other systems so anyone can send in data and not have to worry where it is coming from. Stateful services require both the consumer and the provider to share the same consumer-specific context, which is either included in or referenced by messages exchanged between the provider and the consumer. The idea of SOA departs significantly from that of object oriented programming, which strongly suggests that you should bind data and its processing together. webservices.xml.com /pub/a/ws/2003/09/30/soa.html   (4598 words)

.NET Architecture Center: Service Oriented Architecture The goal for Service Oriented Architecture (SOA) is a world-wide mesh of collaborating services that are published and available for invocation on a Service Bus. These benefits are delivered not just by viewing service architecture from a technology perspective or by adopting Web Service protocols, but also by requiring the creation of a Service Oriented Environment that is based on specific key principles.

Java(TM) Boutique - Service Oriented Architecture - Part 1 Services also define a schema for the input to be supplied to the Service by its consumer. Services are defined as a set of well-defined interfaces, which are generic in nature. The inherent nature of SOA is that Services work with an extendible Schema and thereby can cope with various different types of entities that the Service is dealing with. javaboutique.internet.com /tutorials/serv_orient   (909 words)

What is Service-Oriented Architecture? - A Word Definition From the Webopedia Computer Dictionary This is the first in a series of papers intended to help you better understand the value of a service-oriented architecture (SOA), and to develop a realistic plan for evaluating your current infrastructure and migrating it to a true service-oriented architecture. Though built on similar principles, SOA is not the same as Web services, which indicates a collection of technologies, such as SOAP and XML.

Service-Oriented Architecture ZDNet.com SOA purists will point out that nobody really even has attained what can be considered "service-oriented architectures," and we'll probably never see it. Services can now be developed, published, and consumed by entities anywhere across the globe, and the economies gained through leveraging standardized, reusable, and loosely coupled services will level the playing field between North American, European IT shops and those in emerging regions such as India and China. SOA is not an end in and of itself, but a methodology, or way of thinking about loosely coupling and aligning systems to meet business process requirements. blogs.zdnet.com /service-oriented   (7361 words)

Service-Oriented Architecture The Service-Oriented Architecture (SOA) is an accepted industry model for representing applications on the network as re-usable services. In all cases, requests are made of the services by a calling application that expects some form of reply. For example, a WSDL representing a remote Web service from a non-mainframe application can be identified, automatically parsed and converted to re-usable mainframe COBOL copybooks and programs which can be integrated with existing mainframe applications to leverage functionality found on other computing platforms. www.neonsys.com /solutions/service_oriented_architecture.asp   (278 words)

Web Services and Service-Oriented Architectures The advent of Web Services and service-oriented architectures makes "keeping up" all the more important, because these technologies are fundamentally changing the way we build our internal systems—those that support our organizations—and how internal and external systems will interact. He is also the author of a book that explains Web Services and service-oriented architectures in an easy-to-understand, a non-technical manner.

Understanding Service-Oriented Architecture SOA is a relatively new term, but the term "service" as it relates to a software service has been around since at least the early 1990s, when it was used in Tuxedo to describe "services" and "service processes" (Herzum 2002). Service consumers are not concerned with how the service goes about executing their requests; they expect only that it will. It is important for service designers and developers to understand the concepts of SOA, so that they can make the most effective use of Web services in their environment. www.developer.com /design/article.php/2207371   (1149 words)

Service-Oriented Architecture: Beyond Web Services @ JAVA DEVELOPER'S JOURNAL The problem with using Web services exclusively in a service-oriented architecture is that developers have to wrap any functionality they want to expose as a Web service. This makes sense in cases where the service is built using a foreign technology or is supplied by a different vendor, but ideally you would try to avoid the overhead of packing and unpacking data into XML for services running on the same infrastructure. To this end, the main requirement of an SOA is that the interface to the services is decoupled from the implementation. java.sys-con.com /read/44368.htm?CFID=33259&...   (2730 words)

SOA (service-oriented architecture) A service-oriented architecture is a way of connecting applications across a network via a common communications protocol. A selling point of an SOA is code reuse - developers have only to figure out the interfaces for existing applications, rather than writing new applications from scratch each time new business rules are developed. It would be more interesting to hear how others have moved SOA into their organziations, it's governance, management, and subsequent realized business value/risk mitigation. www.networkworld.com /details/6187.html   (931 words)

Service-Oriented Architecture - Architecture - CIO Magazine Jan 15,2004 And those services shouldn't have too fine a granularity—that defeats the goal of services, which is to function at a higher, business-process level. The services are loosely coupled (meaning that an application doesn't have to know the technical details of another application in order to talk to it), have well-defined, platform-independent interfaces, and are reusable. Buskard, on the other hand, has built his company's SOA without Web services, as none of his internal or external customers are asking for them at this point (though he's keeping his ear to the ground in case they do later on). www.cio.com /archive/011504/soa.html   (168 words)
