Restful And Web Services In Enterprise Application Integration Applied Research

On the 1970s and 1980s, the implementations among systems are different. There are so many different application program interfaces among systems. Besides that, the message format is hardly to be unified. That means the data, applications and business processes are difficult to be integrated. Those systems are became so many "information islands", because they can not cooperate with each other well. Enterprise Application Integration (EAI) let everybody feel that things could be work out, but it came out a series new problems which are includes that most of integration solutions are close-coupled, there are a large number of technical documentation which the developers need to read and learn, the protocol of application and transportation are became more and more complicated, and the interactivity and scalability of systems still couldn't be solved. Meanwhile, a lightweight Web Services the RESTful Web Services began to be widespread concern.The advantage of RESTful Web Services are:it does not require to use the SOAP protocol which is so bulky, it does not require to establish a large of XML messages, what you have to do is just designing identifier for each unique resource in order to call them by enterprise systems in the future. Second, it can be implements by any computer languages just like C, Javascript, Java, and so on. Third, RESTful Web Services support for caching very well, it can take advantage of the cache control head, thus reducing the demand for bandwidth. Fourth, each request is independent and stateless, once invoked, the server side does not keep any conversation in order to avoid the logic error occurred, that enhanc the system scalability. If we can combine the RESTful Web Services technology and enterprise application integration together, we can find the way a better solution to the existence of many problems which we mentioned above.The purpose of this research is to analyze the status of enterprise application integration and its technical features, to combine the RESTful Web Services technology into the enterprise application integration to improve the traditional solution, proposed a new resource oriented framework of enterprise application integration, and verify the feasibility of the new framework through an example.
