Research And Realization Of Middleware Based On SOA

With the economical developement,the requirement of civil automazation is increasing at speed of geometric progressing. There are two core issues faced by the fields of information construction; first, how to improve productivity of development to meet the challenge of increasing rates of change; and second, how to meet the changing needs of customers. The business-oriented application integrator middleware can dopt a kind of definition to achieve the customers'specific requirements , ensure expandability; and be consistent with requirements analysis ; This kind of middleware have the ability to keep program structure and the data storage model separate,as well as to reuse existing definition components and extend definition to meet future customer needs.As to the middleware based on the structure of the multi-layers,the physical coupling degree of the system is relatively high,which run against the distributed application development; In the face of new customers or new demand by the addition of interactive equipment,the system need for re-development;The support data which is binded to the underlying data directly,is unable to carry out effective multiplexing.Due to the above situation, a middleware platform solutions based on Service Oriented Architecture(SOA) is proposed,and its research and implementation process is presented.This paper firstly studies the technology,the reaearch status and development trend of the middleware,analysises the significance of this issue;Second, this paper discusses the concept technology and features of SOA, explains the significance of the SOA's application;The last but one,the paper focuses on the methods of Services Oriented Analysis and Design(SOAD),gives a hybrid modeling method and its modeling process,the method is based on SOAD combining the advantages of object-oriented technology;Finally,the paper designs a system architecture with a low coupling degree and presenteds its research and implementation process.The system has a good scalability and portability, and can be easily deployed. It ensures the accumulation of application software knowledge,realizes business reuse,and shortens the period of application software development.
