Research And Implementation Of The SOA Services Integration Based On SCA

SOA (Service-Oriented Architecture, service oriented architecture) is in last few yearsin a software system structure based on the popular architecture, standard, flexible, looselycoupled SOA theme word, it will completely change the existing IT architecture. At present inthis field have proposed a variety of technology, one of the most popular technology is one ofthe SCA (Service Component Architecture service component architecture) technology,SCA is composed of IBM, BEA, Oracle, IONA, SAP and other18companies jointly releasedon SOA service construction, assembly code, it specifically for SOA design. It simplifies therealization of service component programming model, these components can use differentprogramming language. For enterprise applications, SCA also provides critical infrastructure,such as security, transaction, reliable call. These applications make the enterprise applicationdevelopment has become more convenient. SOA business function is defined as a series ofservices, and from this a series of service assembly together to meet specific business needs,SCA technology at the same time to realize service and assembly services provided by themodel, using SCA to build the system embodies the advantages of SOA structure.This paper mainly studies and discusses the SCA standard in the construction of SOAintegration framework in use. The author first introduces SOA and SCA basic concept,through to the SCA and other technical comparison, demonstration based on SCA integrationadvantages, on the SCA programming specifications, based on a design based on the SCA,use SDO (service data objects), combined with DAS (data access service applicationintegration) architecture, this architecture can solve the SOA application integration and dataservice assembly programming problem; on the integrated architecture, components, modules,interface properties, reference, service, connection, bind SCA elements such as construction,the data in SDO map, DAS model, data object contains the content, type and attribute, theapplication of sequence and other key issues made a detailed study of the. Finally, in myfamiliar examination management system as example, demonstrates how to use SCA, SDOand DAS application integration.
