摘 要
學生成績是一個教育單位不可缺少的部分,它的內(nèi)容對于學校的決策者和管理者來說都至關(guān)重要,所以學生成績系統(tǒng)應該能夠為用戶提供充足的信息和快捷的查詢手段。但一直以來人們使用傳統(tǒng)人工的方式管理學生成績，這種管理方式存在著許多缺點,如:效率低、保密性差,另外時間一長,將產(chǎn)生大量的文件和數(shù)據(jù),這對于查找、更新和維護都帶來了不少的困難。
隨著科學技術(shù)的不斷提高,計算機科學日漸成熟,其強大的功能已為人們深刻認識,它已進入人類社會的各個領(lǐng)域并發(fā)揮著越來越重要的作用。作為計算機應用的一部分,使用計算機對學生信息進行管理,具有手工管理所無法比擬的優(yōu)點.例如:檢索迅速、查找方便、可靠性高、存儲量大、保密性好、壽命長、成本低等。這些優(yōu)點能夠極大地提高學生成績管理的效率,也是學校的科學化、正規(guī)化管理,與世界接軌的重要條件。
本文論述了VB6.0可視化開發(fā)軟件工具下分析、設(shè)計、開發(fā)大中專院校的學生成績管理系統(tǒng)的過程。通過對計算機硬件和軟件解決方案的論證，對應用領(lǐng)域進行調(diào)查分析，參考各種資料和進行數(shù)據(jù)庫編程實踐，在指導老師的幫助下，已經(jīng)基本上成功地實現(xiàn)了設(shè)計要求，實現(xiàn)了利用計算機對學生成績管理，主要包括對學生各種信息的添加、修改、刪除和查詢，以及對學生成績信息的打印等功能。該系統(tǒng)基本上滿足了學校在學生成績管理方面的需求，用戶界面友好。此系統(tǒng)更加貼近信息電子化處理，從而降低了人工勞動并增加了信息的準確性。

Abstract
Student achievement is a essential part educating an unit , its content all all-important , ought to can therefore student achievement is systematic as for school decision-maker and director for the consumer provides sufficient information and rapid inquiry means. But always in the past people is using artificial way of tradition to manage student achievement , this there is existing a lot of shortcoming in supervisor mode, such as: Inefficient , keep secret nature is bad , time is besides once long, will produce large amount of document and data, with regard to, this seeks , renews and defends the difficulty having brought about quite a few.

Rise , computer science are gradually mature with the science and technology ceaselessness, whose function big and powerful already, already have entered each human society fields, conduct oneself deep cognition , it and are bringing the more and more important effect into play. The part being computer applications, uses a computer to carry out administration on student information , has unable parallel handwork administration merit. For instance: The retrieval is prompt , seek reliability is high , store reserves conveniently, to keep secret greatly, nature is good , life-span is long , cost waits low. And these merit is able to improve the efficiency that student achievement manages tremendously , is also the school scientification , regularization administration, the world receives important track condition.
The achievement analysing , designing , developing student of important technical secondary school universities and colleges under the VB6.0 Visualization exploitation software implement the main body of a book has been discussed manages systematic process. By the demonstration resolving a scheme's to the computer hardware and the software, the investigation being in progress to application field analyses , the programming consulting the various data and carrying out a data base puts into practice, have realized design demand already mainly successfully , have come true making use of computer to student achievement administration under the help guiding a teacher,include the functions such as adding , revising , deleting and inquiring about, as well as to student achievement the information printing to various information of student mainly.Being system's turn to have satisfied school need managing aspect in student achievement , the consumer interface mainly is amicable. This system further presses close to information electronization treatment , the accuracy thereby, having reduced manpower physical labour and having increased information's.


Key words: Student achievement manages system, function , characteristic , data dictionary.
