| Web Service is considered as an important technical leap in the field ofdistributed computing, which represents a new-generation softwarearchitecture mode for developing application software on Internet. WebService solves the problems we meet when we use the traditional distributedtechnology such as CORBA and DCOM, mainly including the complexity topass through firewall, protocol and the integration of different platforms.According to this viewpoint, this article analyzes the present status of websecurity in college and the requirement for distributed data management, andthen puts forward a sort of distributed information system based on WebService architecture, which solves the problem on how to make data passthrough firewall. The users can apply the reserved logical units to assembletheir own application program, and realize the second development of theirown. The article puts more weight on the efficiency and security in applicationof Web Service, and advocates to enhance the efficiency and security of WebService by making use of SOAP extension, high-speed data cache andexploiting additional business logical module. The system can make good useof resources in the present web conditions, and equip the system with betterintegration expansion and extension.The above system scheme can meet the requirement of college and enterprises to manage distributed data and their second development, meanwhile it has the merit of lower cost and simple construction. |
