This paper uses Ajax without refreshing technology to eliminate the waiting time. At the same time, it uses the Oracle 11g database server in PL/SQL programming to create a stored procedure realization of data paging query. With these two technologies combined together, by querying or computing and transmitting the necessary part of the data to the WEB server, the client can use the asynchronous Ajax communication technology to obtain WEB server without refreshing the data, which shortens the waiting time of the users, and improves the application performance.
