This site will help you get started with a service-oriented architecture (SOA) using Web services. It features free articles, services, and product listings that can be used to develop a service-oriented architecture using Web services.

SOA is an architectural style whose goal is to achieve loose coupling among interacting software agents. A service is a unit of work done by a service provider to achieve desired end results for a service consumer. Both provider and consumer are roles played by software agents on behalf of their owners.

SOA is not complex. You are just dumb.

Welcome to SOAPatterns.org, a site dedicated to the on-going development and expansion of the SOA design pattern catalog.

Strong coupling occurs when a dependent class contains a pointer directly to a concrete class which provides the required behavior. Loose coupling occurs when the dependent class contains a pointer only to an interface, which can then be implemented by one or many concrete classes. Loose coupling provides extensibility to designs. A new concrete class can easily be added later that implements that same interface without ever having to modify and recompile the dependent class. Strong coupling does not allow this.

A WCF Service is composed of three parts — a Service class that implements the service to be provided, a host environment to host the service, and one or more endpoints to which clients will connect.

In computing, service-oriented architecture (SOA) has different non-standard and openly-debated definitions. (no shit)
