摘要
隨著計算機技術(shù)的發(fā)展，人類在生產(chǎn)、生活的各個領(lǐng)域都應(yīng)用到了計算機，這充分體現(xiàn)了計算機高效、全面、快速處理信息的能力。而作為計算機最大的應(yīng)用領(lǐng)域——數(shù)據(jù)庫管理系統(tǒng)（DBMS），在現(xiàn)代計算機系統(tǒng)已被作為主要的系統(tǒng)軟件之一。
本文討論了一個數(shù)據(jù)庫系統(tǒng)的設(shè)計實例,并利用對數(shù)據(jù)庫的操作,開發(fā)一個商業(yè)信息系統(tǒng),本系統(tǒng)使用Visual Basic6.0做前臺應(yīng)用程序，Microsoft Access2000做后臺數(shù)據(jù)庫，使用ADO技術(shù)來連接數(shù)據(jù)庫。系統(tǒng)中使用DataGrid控件、MsChart控件等ADO控件以及DataReport控件、DTPicker控件等具有數(shù)據(jù)綁定功能的控件與數(shù)據(jù)環(huán)境配合使用。本文主要內(nèi)容如下：先對開發(fā)軟件Visual Basic 6.0 面向?qū)ο蟪绦蛟O(shè)計作了簡要介紹，同時詳細說明了本系統(tǒng)所用的Visual Basic 6.0數(shù)據(jù)庫系統(tǒng)及開發(fā)等相關(guān)知識。然后對系統(tǒng)進行需求分析，畫出功能模塊圖，給出部分表。接著給出了程序設(shè)計的某些界面和部分代碼。最后對此次設(shè)計進行了簡明，扼要的總結(jié)。
關(guān)鍵詞：前臺應(yīng)用程序、數(shù)據(jù)庫、ADO、數(shù)據(jù)環(huán)境






Abstract
With the rapid development of computer technology, computer technology has been applying to all over the fields of human, such as life,study, production, and so on. It has proved that the computers are efficient, comprehensive and prompt in processing and managing information. AS Data Base Management System (DBMS) is the best extensive in the application field of computer, which has been used as the one of most important system software in modern computer system.
The article is an instance for designing a database system, it introduces the development of a mercantile information system based on the operations of database. The system used Visual Basic 6.0 as Proscenium Application, and Mocrosoft Access2000 as Background Database, and ADO technic to connect with database. And we also used DataGrid control, MsChart control which is ADO control, and DataReport control, DTPicker control which can connect with Data Environment. In this article the main contents as the follows: First there is brief introductions of Visual Basic 6.0 and the programmer facing to object, also including the full and necessary recommendation of basic knowledge of database, then we proceed the need analysis of the system,draw out the diagram about the function module, also we have shown part of tables.and then give out some forms and part of code about the programmer. Finally, a simple and compendious summary is presented.
Keyword: Proscenium Application, Database, ActiveX Data Objects, Data Environment
