Web request of interface to allow user content to have a look around relevant data base. Interface this make user can connect through appointed one JDBC driver or URL with a data base. Then, the application program will allow users to have a look around all forms defined in the data base , And can choose any form to deal with its datum . Equally, user can also input SQL inquire the sentence and look over that these are inquired about and operate the tabular data produced . Until what user use conversation any time, must guarantee user can disconnection data base very easily, And connect to another data base . Keyword: MVC Design the mode Multilevel structure. 2
