And maintenance and update the database system requires a certain amount of funds, the funds should be posed of item bank beneficiary students to pay. Therefore, the urgent need to create a convenient operation, perfect function of database user billing system, which can facilitate users to buy exercises, and as the owner of database system produces an ine, at the same time the question bank system capable of longterm service to provide economic security to students. This system uses Java as the development language, as database system, the development environment is , the server using , developed a database user charging system based on B/S structure of Web technology.Key words: database charging。因此，迫切需要?jiǎng)?chuàng)建一個(gè)操作方便、功能完善的題庫(kù)用戶(hù)計(jì)費(fèi)系統(tǒng)，它可以方便用戶(hù)購(gòu)買(mǎi)習(xí)題，并為題庫(kù)系統(tǒng)的所有者帶來(lái)一筆收入，同時(shí)為題庫(kù)系統(tǒng)能夠長(zhǎng)期服務(wù)于同學(xué)提供經(jīng)濟(jì)上的保障。網(wǎng)上答題不僅給學(xué)生們的學(xué)習(xí)帶來(lái)了方便，而且可以減少紙張的使用，節(jié)約了資源。中文題目：題庫(kù)用戶(hù)計(jì)費(fèi)系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)外文題目：THE

要在網(wǎng)絡(luò)技術(shù)逐漸滲入社會(huì)生活各個(gè)層面的今天，網(wǎng)上題庫(kù)系統(tǒng)可以借助于網(wǎng)絡(luò)進(jìn)行傳播。 通過(guò)遠(yuǎn)程登錄題庫(kù)系統(tǒng)進(jìn)行網(wǎng)上答題的學(xué)習(xí)方式受到了越來(lái)越多學(xué)生的青睞。而題庫(kù)系統(tǒng)的維護(hù)與更新需要一定的經(jīng)費(fèi)，這筆經(jīng)費(fèi)應(yīng)該由題庫(kù)的享用者——學(xué)生來(lái)買(mǎi)單。本系統(tǒng)以
