-摘要-
隨著科學(xué)技術(shù)的迅猛發(fā)展和管理水平的不斷提高，計(jì)算機(jī)已經(jīng)被廣泛應(yīng)用于日常管理之中，它的運(yùn)用不斷改進(jìn)著管理模式，使管理日趨程序化、規(guī)范化、現(xiàn)代化。對(duì)一個(gè)企業(yè)來說，為了使數(shù)據(jù)在企業(yè)中能更有效的被利用、被管理，引入計(jì)算機(jī)輔助管理已是一種必然，企業(yè)管理信息系統(tǒng)的開發(fā)迫在眉睫，其中為企業(yè)實(shí)施全面質(zhì)量管理，落實(shí)技術(shù)經(jīng)濟(jì)責(zé)任制提供及時(shí)、準(zhǔn)確、可靠和一致的信息，企業(yè)數(shù)據(jù)信息管理系統(tǒng)成為企業(yè)管理系統(tǒng)中的重要組成部分。
本系統(tǒng)主要實(shí)現(xiàn)了以下功能①數(shù)據(jù)錄入：用戶按照所需要的工程規(guī)格輸入條件，系統(tǒng)根據(jù)條件按照最底層數(shù)據(jù)表計(jì)算出本次操作所需的數(shù)據(jù)加載到事先設(shè)置好的空數(shù)據(jù)表中。②數(shù)據(jù)查詢：用戶給定查詢的數(shù)據(jù)條件，系統(tǒng)在查詢DBGird中示出查找到的數(shù)據(jù)。同時(shí)可把數(shù)據(jù)添加到專用表，進(jìn)行多工程的數(shù)據(jù)管理。③數(shù)據(jù)匯總和報(bào)表功能：根據(jù)企業(yè)實(shí)際要求出匯總的數(shù)據(jù)的報(bào)表顯示，同時(shí)匯總完成的信息可以打印成報(bào)表，用于文件存檔或者便于企業(yè)管理者管理數(shù)據(jù)信息。④物理表管理：對(duì)物理表進(jìn)行添加、修改、備份和刪除等工作，便于數(shù)據(jù)庫(kù)的長(zhǎng)期正常運(yùn)行。⑤系統(tǒng)權(quán)限維護(hù)：在登陸進(jìn)系統(tǒng)時(shí)有權(quán)限的要求，高級(jí)的權(quán)限可以管理低級(jí)的權(quán)限，加強(qiáng)了企業(yè)信息的保密工作。
本系統(tǒng)的開發(fā)使用 MICROSOFT公司的 VISUAL BASIC作為開發(fā)工具,利用其提供的各種面向?qū)ο蟮拈_發(fā)工具,尤其是數(shù)ADO技術(shù)能方便而簡(jiǎn)潔操縱數(shù)據(jù)庫(kù),通過這些技術(shù)在短時(shí)間內(nèi)建立系統(tǒng)應(yīng)用原型,然后,對(duì)初始原型系統(tǒng)進(jìn)行需求迭代,不斷修正和改進(jìn),直到形成了這個(gè)用戶滿意的可行系統(tǒng)。

-------------ABSTRACT--------------
With science and technology swift and violent development and constant improvement of the management level, the computer has already widely used in everyday control, its application updates the management mode, enable managing the procedure , standardizes , modernization day by day. To an enterprise, for make data can a valid one utilize , manage among enterprise, it has already been a kind of necessity to introduce the computer-aided management, the development of the management information system of enterprises is extremely urgent , among them implement the total quality control for enterprises , implement the technological economic responsibility system and offer prompt , accurate , reliable and unanimous information, enterprise's data information management system becomes the important component in enterprise's administrative system
This system has realized the following function mainly ①The data are input: Users input the condition according to the project specifications needed, system is it operate according to terms necessary data is it get in advance setting up kind empty data listing to load this time to calculate out according to the bottom data list. ②The data are inquired about: Users give the data terms inquired about definitely, the system shows the data that finds out in inquiring about DBGird. Add the data to the special-purpose form at the same time, carry on the data management of many projects. ③The data are gathered and report form function: Demand according to enterprise report form of data gathered to appear show message finished to gather at the same time can be typed into a report form actually, used in the file files or a convenient enterprise's administrator manages the information of the data④Watch manages physics: Go on add , revise , back up and work of deleting etc. to physics form , benefit the long-term normal running of the database. ⑤The systematic authority is safeguarded: There is a demand for the authority while landing and entering the system , can manage the low-grade authority in advanced authority , have strengthened the security work of enterprise's information

The development of this system uses VISUAL BASIC of MICROSOFT Company to utilize its various kinds of target -oriented developing instruments offered as the developing instrument, count ADO technology can convenient succinct to handle database , set up through technology the system use the prototype within short time especially, then, carry on the demand to change and take the place of to the initial prototype system , is revising and improving constantly, until forming the feasible system that this user is satisfied with.

Keyword:Administrative system , project , controlling part,ADO
