In the introduction dynamic homepage procedure development and in the data accessing technology base, proposed the network English test system composition and the structure, elaborated the system design proposal, the realization method as well as use development kit and correlation technology, but also analyzed the partial links programming with emphasis. Have an examination system adopt B/S mode development, need to install the customer end originally, authorized users to log in to the system through the browser, thus begin the normal examination. This system was structured with SQL Server database platform by a Windows 2000 operating system based on Microsoft, Internet information management device. The performance that the products of Microsoft are excellent has offered the high-efficient and steady running environment for this system; make this system no matter at the speed, apt to behave with the sex or in handling capacity of the data remarkably of operation. This system adopt a great deal of technological scheme is it have an examination normal going on steady to guarantee. Overall fault-tolerant treatment makes having an examination and gets orderly control in procedure of the homework, can carry on the effective shielding to users mistake operation; In the course of examination, forbid examinees to break the browser, prevent the examinee from operating and causing the answer to lose by mistake; Is it is it limit to go on to operate by right key to mouse, is it have an examination systematic user integrality of interface to guarantee; In addition system offer test time
