Design And Implementation Of Remote Education System In Baoji Vocational Technology College

With the increasingly development of computer network technology, modern distance education is rapidly spread from country to country. With the expansion of distance education courses and at the same time, the traditional three layers architecture independent system in large heterogeneous, distributed system requirements. In response to these changes, based on the analysis of the fifth generation of the development trend of intelligent remote education platform, this paper puts forward the solution is to use SOA services architecture building remote education management platform, integrate the comprehensive business make it become a kind of interconnected, reusable business tasks or services, and greatly increase the flexibility of the system, can in the case of without considering the interface problem using a service to replace another service, truly achieve the tightness combination of information technology and education strategy, dynamic adapt to complex policy changes.Firstly, this paper studies the J2EE framework and characteristics and service interface of service-oriented architecture (SOA). It analysis the Baoji college needs from the recruit students management, educational administration, financial management, course selection, registration, performance management, exam management, news management and system management after analyzing the functional requirements according to the eight modules according to the teachers, students, administrators, the three roles in use case analysis, business process analysis. Then according to the principle of service-oriented architecture (SOA) has carried on the overall design of the architecture to teaching platform from business data model is established to realize the data service, specific design method is presented according to the characteristics of distance education, combining with the SOA architecture, dynamic strategy library component, artifacts, test registration component design method of elective courses, and the system database design are completed. Implemented on J2EE platform in the system implementation, completion of the entire system architecture design, according to the process of software engineering design thought is given business logic and the presentation layer design method and code implementation, and analysis needs operating several of the most commonly used method to realize the function. Finally in Loadrunner test, test results show that the system developed in this paper can meet the design requirements.
