| Along with the higher vocational colleges teaching reform and development, and the wide application of network technology and multimedia technology, as well as the relevant documents of the spirit of National ministry of education and the Liaoning department of education, the fine demonstration courses will be established in higher vocational colleges. Mainly depending on excellent teachers team, rich teaching content, advanced teaching method, the dominant basic materials, the scientific teaching management, and modern teaching platform, High-quality demonstration course realizes a comprehensive course construction of system, for the purpose of improving the whole quality of teachers' team as the forerunner, taking the scientific and advanced teaching idea as the premise, and with the modern teaching environment as the basis, facing the students' comprehensive quality improvement.As an important part of exquisite course website, playing the role of checking the students' autonomous learning and reducing their burden, Network examination system has been the research subject of teaching management system. Previous network exam system are based on objective topic primarily, it is difficult to check out the students' learning a course actual level.So adding the evaluation mechanism for subjective question in exam system is the research direction.Relying on the development projects of Database Technology exquisite course website and supporting Network Exam System of the Liaoyang Vocational Technology Institute, this paper analysed the current Web application development mainstream JSP technology and related theory, combined with the software architecture, design model, developing method based on J2EE framework to study on the practical application of MVC design patterns, designed and implemented the database technology" exquisite course website and network examination system.Based on the analysis of the demand, adopting the E-R chart data abstraction, through the design system data model to describe and generate database, and completed the database server implementation and performance optimization. Based on J2EE application of Struts, the Web application framework through mapped decomposition the application's data model, user view and business control logic, realized the parts of the loose coupling, thus greatly enhancing the code reusability and efficiency of development.Through the research for the artificial intelligence technology, natural language understanding and related technology, the paper designs and the develops the online examination system with the automatic scoring function with the subjective questions, this system realizes the exam management, intelligent, online examination, automatic scoring integration, is a function comparatively perfect network exam system which not only can be used with exquisite course site, also can independent into a simple network examination system. Intelligent network exam system is the key of this study, basically solved the defects of lack of subjective topic score in the the current network exam system.The Database Technology exquisite course Website ot Liaoyang Vocational Technical College is set up and and built a unimpeded learning platform and enrich the students' learning time, expand the communication between teachers and students, play a huge role in supporting. Exquisite course website and the network examination system research, development and implementation, have high practical value and a certain significance for the construction of exquisite course website in other higher vocational colleges, course with. |
