The Application Development And Integration Based On Service-Oriented Architecture

SOA is developed from original distributed computation based on components. Nowadays it has been wildly accepted as a industrial standard. theoretically, SOA is a favor option by the developers because of its concentrating on the reusable of software. With the help of the well-defined mechanism or APS (Application Platform Suite) which is integrated with applications, it is possible to integrate a single application into a cluster of servers. An abstract layer is created in the integration progress. It covers the complex details in the application.So that developers need not care about such information like programming language, operation systems and databases used in the products. The only issue they should work on is the interface described by the service. Then they can reach the goal to integrate the loose couple process service. The advantages of SOA are the reusability, flexibility and complication. After years of development, the advantages of SOA are outstanding in series of application projects. Just like Gartner Group has said, "SOA is an important issue in modern application development area. In 2008, SOA will be the domination software engineering development method, mainstream enterprises now should invest more on understanding and apply SOA development technology."This thesis focuses on the relevant concept of the SOA, the features, the advantages, the history, and the main technologies. With the help of the practice works, we demonstrate steps to develop SOA. We also present the problems and difficulties we might meet during the development progress and the principle in SOA deployment and development for the enterprise purpose. With distant to take petroleum sell company marketing system dispose SOA as example , through write 2000 over program codes, have realized in this enterprise that build up and dispose existing resources of enterprise with SOA,We discuss the situations suite the SOA and problems which are existing in current researches. In the end, we present the future work of SOA. Integrated with modern activate service technology, we also discuss the feasibility of the intelligent SOA architectures in the future.
