The Study And Achievement Of The Elective System Base On Network

According to the theoretics of elective regulation under the conditions of the credit system,the paper firstly analyze the basic principle of web database and the technique of network security, and then makes a systematic expatiation in aspects of the design thought and runnahle principle of the elective system base on the network environment, finally further realize a managing system of the common elective on network.The actualization of credit system is one of important measure which is adopted in the reform of the teaching governance in the advanced school, it will pick up the quality of education and set forward the reform of advanced education. Elective regulation is the precondition and foundation of the credit system.and is also the elementary character in the teaching supervisal of the credit system.The quality of elective system is made up of the operational research orderliness, organizing information and interface design etc..In the typical case,web application keeps to three layer architecture model.It mainly incarnates three logistic area as follows: presentation layer,control layer and application logic layer. JDBC is an universal bottom program interface which holds out basic SQL function,and it provides an uniform user interface in the different database module hiberarchy.When connecting database through drive, there are different approaches as follows: (1) JDBC-ODBC bridge, (2) part-Java, native-API, (3) mediator-database accessing server, (4) JDBC-Net pure Java.JSP personates an important role in the web techniques, it can separate the express from realization logic through applying the script element and object oriented subassembly.JSP provides a very excellent web frontend separate technique.The system security are one of the major issues which will be resolved in the paper, the applications of the one-time password system and the network firewall technique ensure the security, secrecy and stability of the system.Because the elective system bases on local area network or Internet, the stability, architecture and data algorithm of the system should be aborative devised and realized.At the same time, the culture plan of the person with ability, teaching resource and course scheme are dynamic development, so the system require advanced and logical technique measures.These measures include the mark and identity validation of the user, the dynamic track of the elective process, the equitableness algorithm and optimizing resource, accident management ect..The research aims at solving the typical issue existing in the management of elective course base on network environment, improving sufficiently the quality and efficiency of the educational administration, promoting positively application and study of network technology, and enhancing comprehensively the managing quality of the elective course, making the actualization and application of the elective system more scientific and standard.
