Abstract


With the rapid development of information technology, enterprises are facing increasingly complex IT environment, and there is an urgent need for a loosely-coupled and platform-independent system to deal with rapid changes in the outside world. As a result, companies are increasingly concerned about the service-oriented architecture (SOA) in the hope of taking advantage of the SOA to enhance their business agility and reducing the cost of developing an information system. In the SOA, resources are an independent service which is accessible to the other members within the network through the standard manner. Compared with the traditional system architecture, the SOA sets a more flexible and loosely-coupled relationship among resources.Based on the idea of enterprise service bus (ESB) and the concepts of the SOA and its stratified realization, the thesis introduces ESB into the stratified realization of the SOA and puts forward an ESB-based lightweight SOA. Focusing on the problems of low recall ratio and long query time in the service semantic matching, the thesis presents a quality-based service semantic matching algorithm to improve the matching rate and shorten the response time of the SOA. Also, based on the shared model of SOA safety service, solutions to the safety problems in the SOA are proposed. The identity management mechanism based on SAML and a cross-domain access program are put forward to ensure the safety of identity management in the SOA; the improved digital envelop technology is proposed to ensure the safety of XML documents in the SOA; the SOAP message monitoring mechanism is applied to ensure the security of information in the SOA. Last, based on the SOA, the thesis accomplishes the design and development of the database system for Chengdu Aircraft Industrial Group, which achieves the integration of the Group’s old systems and makes the system more safe, stable and agile.
