SCA provides developers with a simple, business-oriented, model for creating systems based on a service oriented architecture. It manages infrastructure complexities such as transactions, security and reliable messaging and frees the developer to focus on providing business function. The solutions developed using SCA can be changed declaratively to alter infrastructure capabilities or application configuration properties to meet changing business requirements. For example, infrastructure capabilities such as security policies may change from one environment to another and can be changed without the need for re-implementation. Application configuration may also be changed in this way, for example, the currency quoted by a stock quote feed may be changed though the SCA configuration mechanism.
SCA divides up the steps in building a service-oriented application into two major parts:
Tuscany implements SCA in Java and C++. For more information about each implementation or to get involved please refer to the following links.
A PHP implementation for SCA is also available at <link for PECL>.
