【正文】 II ACCOUNTING SYSTEM SOFTWARE ON COMPUTER LAB Abstract This thesis focus the study on puter lab accounting system which is based on C/S structure, designed and developed by Access 2021 databases and Visual . In the article, author mainly analyzes some basic functions and position of this system, which including system demanding analysis, system design principle, system design idea, description of functional module, Database design, processes of system munication and agreements of munication. In addition, this thesis introduces briefly on use of Visual , Access 2021 database, and Visual , meanwhile, lists some programming codes to explain the realization process of this system applying the programs. Key words C/S structure, Access 2021, Visual , munication agreement 1 第一章 緒論 選題的背景和意義 隨著計算機 技術(shù) 的 日月更新，越來越多的人們注重加強對 計算機 知識的學(xué)習(xí)， 為了滿足 學(xué)校學(xué)生 或者社會學(xué)員的需求，許多 網(wǎng)吧 都 紛紛 對外開放， 實行 計時收費。 網(wǎng)吧計費系統(tǒng) 目 錄 摘 要 ............................................................
