【摘要】
隨著計算機技術(shù)的飛速發(fā)展，計算機在信息管理方面也應(yīng)用的普及，信息管理系統(tǒng)的開發(fā)在強調(diào)管理、強調(diào)信息的現(xiàn)代社會中也顯得越來越重要。因此，利用計算機支持單位高效率地完成庫存的理的日常事務(wù)，是適應(yīng)現(xiàn)代化管理制度的要求、推動管理方式走向科學化、規(guī)范化的必要條件。
在當今的信息社會，隨著信息的不斷增長和管理上對信息的要求，信息管理技術(shù)隨之出現(xiàn)。本論文就是以Delphi7.0為前臺和ACCESS2000為后臺等軟件作為開發(fā)工具，以煤氣站為對象，開發(fā)一個從某種程度上能滿足管理要求的“煤氣站管理系統(tǒng)”。本系統(tǒng)具有數(shù)據(jù)管理和事務(wù)管理功能。使用該系統(tǒng)，可以方便地進行查詢等方面的管理。快捷地查詢煤氣站的情況，方便煤氣站管理人員對煤氣站的管理情況的現(xiàn)狀有個比較全面的認識，也方便他們的管理，可輔助管理人員決策科學化，從而大大減少了工作量，提高了工作效率。本課題是煤氣站管理系統(tǒng)，主要內(nèi)容包括系統(tǒng)、系統(tǒng)設(shè)置、日常業(yè)務(wù)、查詢統(tǒng)計、幫助等幾個模塊。擬采用的開發(fā)平臺為Windows2000，開發(fā)工具為Delphi7.0+ACCESS2000。

【Summary 】
With the development , popularization which the computer employed too in information management at full speed of the computer technology, the development of the information management system seems more and more important in the modern society putting emphasis on managing , emphasizing information too. So, utilize the computer to support the unit to finish the routine affair that pays attention to held in store with high efficiency, meet the needs of modernized management system , push the management style to move towards the scientific process , standardized requirement. In the current information-intensive society , with the constant growth of information and managerial requirement for information, the information administrative skill is thereupon the appearance. This thesis regards Delphi7.0 as front desk and ACCESS2000 as the developing instrument as software such as the backstage supporter , stand , as target , develop with coal gas one can meet management expectancy " whether coal gas stand administrative system " to a certain extent. This system has data management and functions of management of affairs. Use system this, can conveniently person who inquire management of. Inquire situation that coal gas stand , help coal gas stand administrative staff have pieces of overall understanding to current situation of administrative situation that coal gas stand swift, facilitate their management too, very auxiliary administrative staff's decision scientific process, thus reduced the work load greatly , have improved working efficiency. Subject this whether coal gas stand administrative system, main content include system , system set up , daily business , inquire count , odd pieces of module of helping etc.. The developing platform planned to adopt is Windows2000, the developing instrument is Delphi7.0 +ACCESS2000.
