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.</p> + + <p> SCA divides up the steps in building a service-oriented application into two major parts:</p> + <br/> + <p>* The Implementation of components which provide services and consume other services. SCA supports + service implementations written using any one of many programming languages, both including conventional + object-oriented and procedural languages such as Javatm, PHP, C ++. XML-centric languages such as BPEL + and XSLT, and also declarative languages such as SQL and XQuery. SCA also supports a range of programming + styles, including asynchronous and message-oriented styles, in addition to the synchronous + call-and-return style.</p> + <p>* The Assembly of sets of components to build composite business applications that addresses specific + business requirements. This is performed by wiring together the service implementation components. </p> + + <div align="center"> + <br/> + Click on the diagram for more information. + <br/><br/> + <img src ="images/SCAComposite.png" alt="SCA Composite" usemap ="#scaMap" border="0" /> + + </div> + +<map name="scaMap"> + <area shape ="rect" coords ="75,0,170, 55" href ="sca-interface.html" alt="Interface" /> + <area shape ="rect" coords ="410,0,505,55" href ="sca-interface.html" alt="Interface" /> + + <area shape ="rect" coords ="75,222,160,308" href ="sca-binding.html" alt="Binding" /> + <area shape ="rect" coords ="425,222,511,308" href ="sca-binding.html" alt="Binding" /> + + <area shape ="rect" coords ="245,222,330,308" href ="sca-implementation.html" alt="Implementation" /> + + <area shape ="rect" coords ="108,178,130,187" href ="sca-wire.html" alt="Wire" /> + <area shape ="rect" coords ="280,178,305,187" href ="sca-wire.html" alt="Wire" /> + <area shape ="rect" coords ="455,178,480,187" href ="sca-wire.html" alt="Wire" /> + + <area shape ="rect" coords ="145,105,260,170" href ="sca-component.html" alt="Component A" /> + <area shape ="rect" coords ="320,105,435,170" href ="sca-component.html" alt="Component B" /> + + <area shape ="rect" coords ="0,105,105,170" href ="sca-service.html" alt="Service" /> + <area shape ="rect" coords ="475,105,580,170" href ="sca-reference.html" alt="Reference" /> + + <area shape ="rect" coords ="245,0,307,22" href ="sca-property.html" alt="Property" /> + + <area shape ="rect" coords ="60,60,525,215" href ="sca-composite.html" alt="Composite" /> + +</map> + </section> + </body> +</document> |
