Now, the technical development in hardware in calculator has come to a very high horizontal. But, the long range educate the development of the software to still be placed in the stage in start now, along with this technical continuously thorough development, will beg the better and more perfect software system apply to the long range the education center go to, face to now the network plait distance, database visit in various techniques, for example in the JSP, PHP, ASP, ASP with its development cycle short, access data simple, run - time velocity quick and become the head of numerous the member of web procedures chooses to develop the technique. but because of development the means keeps the view, fleetness with efficiently, also brought the certainly safe hidden trouble. The database is the foundation of the on-line examination system, usually all keeping the important information. Educate the section to keep with the electron data of the school all mostly in every kind of database, they keep the some personal data with these databases, for example student score etc. The on-line examination system database server still controls the impressionable data, including the time of the examination with the subject of exam
