Research Transit Query System Based On J2EE

Public transport query is the important measure which is convinent to the citizen and the travllers.At present,the system of the public transport query is developing very fast in our country.Its basic function has been realized and now it is more and more humanity.As a excellent query system,it must have two factors:first,it can satisfy the demands of the query.second,it must have the high query speed.To satisfy these two factors,we have to make a deep analysis to the system,and choose the best query algorithm,developer tools and the ways of the programme.This paper discuss the public transport query system as the follows:1)it introduces the present research background, the paticular study direction.2)it discuss the developing structure of the public transport query system---J2EE.3)it makes a research to the present public transport's best path algorithm.The author explain the definition of the algorithm and the way of its implement.and she make an analysis of the query speed4)the author combines the development tools and make the programme of the transport query system with the way of Jsp+MYSQL.And it achieves two parts function:Login validation and public transport query.These two parts are different on code,but they have the relations on the functions.It reflects the basic requestion of the programme development. in this article,the author list the programme code of the interralated function in the process of the programme development,and she gives a detail explanation for it.5)at last,the author makes a summary for this inquiry system,and analyse its function,and she points out the future research direction.
