Abstract
Interdynamic assisting in order to offer teacher and student on-line assisted instruction is for the goal of this thesis, Streaming of Video Data to combine most popular one at present, reach the on-line function that talks immediately, and cooperate with the database to reach the functions of on-line making an appointment , management ,etc. , can improve teacher's teaching quality and answer the way to student's question fast , can be reached the two-way
communication and talked through Face by Face, students can also learn through this system whether the teacher is free !, and then putting forward the question on-linly, it is a useful e-learning system on the teaching to have in fact.
In fact, Server end is responsible for ActiveX Control download, the relevant parameter (entity IP ) that and offer bunch to flow, realize carrying bunch and flowing and serving far. Server end has Tomcat webpage server to withstand. Erect the systematic database with MySQL, and make use of MYSQL-Connector to enable JSP webpage to deposit and withdraw DATA in MySQL database.
This systematic way is with the system built and constructed out of MVC structure, represent some components and rely mainly on view, Controller is responsible for explaining Input from user (keyboard and Genius mouse), and tell Model or View to do the proper change. Model is responsible for the place where the behavior and materials with main application program store, the part of the database is as the bridge communicating through JDBC, and utilize JavaBean to become an effective and practical system as the systematic component.
