效率,因此在這種社會(huì)的大環(huán)境下,開發(fā)設(shè)計(jì)大學(xué)生宿舍管理系統(tǒng)迫在眉睫。 6 系統(tǒng)設(shè)計(jì)的背景 、意義及必要性 高 校宿舍是高校一個(gè)不可或缺的組成部分,在當(dāng)今大學(xué)逐年擴(kuò)招的形勢(shì)下,高校中的學(xué)生數(shù)量越開越多,而由于滯后的學(xué)生宿舍管理系統(tǒng),高校出現(xiàn)的管理問題也越來越多,這其中首當(dāng)其沖的就是宿舍用電管理問題,由于宿舍用電管理涉及到諸多方面,且部分高校采取繁瑣的紙質(zhì)記錄人工操作方式,往往耗費(fèi)了大量的人力物力,卻事半功倍,比如西安財(cái)經(jīng)學(xué)院,學(xué)?,F(xiàn)有 17000 余名學(xué)生,但還是停留在宿舍用電管理人員手工記錄數(shù)據(jù)的最初階段,手工記錄對(duì)于規(guī)模小的學(xué)校來說還可以勉強(qiáng)接受,但對(duì)于宿舍用電量信息比較龐大,需要激勵(lì)存檔的數(shù)據(jù)不較多的高校來說,人工 記錄是相當(dāng)麻煩的。 因此我 對(duì)于 基于 vb 宿舍用電 系統(tǒng)的可行性主要是從以下幾個(gè)小點(diǎn)進(jìn)行的分析: 技術(shù)可行性分析 為本系統(tǒng)的開發(fā)我特 別對(duì) 大學(xué)校園 進(jìn)行了深入的調(diào)查研究 , 并且本系統(tǒng)的開發(fā)我利用 Microsoft SQL Server20xx 作為本系統(tǒng)的數(shù)據(jù)庫(kù),它是一個(gè)支持多用戶的新型數(shù)據(jù)庫(kù),適用于大中規(guī)模的數(shù)據(jù)量需求。目前,Windows 下的應(yīng)用軟件無論大小,其安裝程序幾乎均做到了這一點(diǎn)。這樣設(shè)計(jì)出來的程序不易出錯(cuò),而且易于維護(hù)。作為一個(gè)完備的數(shù)據(jù)庫(kù)和數(shù)據(jù)分析包, SQL Server 20xx 為快速開發(fā)新一代企業(yè)級(jí)商業(yè)應(yīng)用程序、為企業(yè)贏得核心競(jìng)爭(zhēng)優(yōu)勢(shì)打開了勝利之門。 SQL 語言結(jié)構(gòu)簡(jiǎn)潔,功能強(qiáng)大,簡(jiǎn)單易學(xué),許多大型的數(shù)據(jù)庫(kù)管理系統(tǒng)都支持 SQL 語言作 為查詢語言。在 Visual Basic 中用戶可以可視地創(chuàng)建數(shù)據(jù)庫(kù)和查詢、 SQL 服務(wù)器程序、 Oracle 數(shù)據(jù)庫(kù)表、使用拖放方法創(chuàng)建視圖,以及自動(dòng)改變列數(shù)據(jù)類型。 , Visual Basic 提供了改進(jìn)的在文件系統(tǒng)中移動(dòng)的程序集,并可創(chuàng)建文本文件和目錄。 Microsoft數(shù)據(jù)報(bào)表設(shè)計(jì)器( Microsoft Date Report designer) 是一個(gè)多功能的報(bào)表生成器,以創(chuàng)建聯(lián)合分層結(jié)構(gòu)報(bào)表的能力為特色。 這些特點(diǎn)使 Visual Basic 成為當(dāng)前流行的計(jì)算機(jī)編程語言之一,因特網(wǎng)上關(guān)于 它 的討論區(qū)或個(gè)人網(wǎng)頁(yè)隨處可見,足見其普及之廣,影響之大。 通過本系統(tǒng)的應(yīng)用,可以加強(qiáng)對(duì) 宿舍電 使用信息的管理,減輕管理員的工作負(fù)擔(dān),提高工作效率。 現(xiàn)在我國(guó)的中小型企業(yè)的用電管理水平還停留在紙介質(zhì)的基礎(chǔ) 上,這樣的機(jī)制已經(jīng)不能適應(yīng)時(shí)代的發(fā)展,因?yàn)樗速M(fèi)了許多人力和物力,在信息時(shí)代這種傳統(tǒng)的管理方法必然被計(jì)算機(jī)為基礎(chǔ)的信息管理所取代,而購(gòu)買大型通用用電管理系統(tǒng),對(duì)中小型企業(yè)來說,有需要付出昂貴的代價(jià),而且用電項(xiàng)目不一定完全符合企業(yè)用電管理的要求,因此根據(jù)企業(yè)目前的實(shí)際的用電管理情況開發(fā)一套用電管理系統(tǒng)是十分必要的。s small and mediumsized enterprises in electricity management level still remain in the printing paper on the basis , such a mechanism already can not adapt to the development of the times, because it wasted a lot of human and material resources, in the information age ,this traditional management approach must be based on puter information management to replace, and purchasing the large general electric management system is for the small and medium enterprises to say, there is a need to pay a high price, and electricity projects may not be entirely consistent with the enterprise using electric management requirements, therefore according to the present actual electricity management to develop a power management system is very necessary. The school as a pioneer in the development of information era, has been widely used puter systems for the ma nagement of various departments together,. As a result, it improves the work efficiency and the management level. Dormitory electricity management system is a typical management information system ( MIS ), and practical management information system. The administrator may update, delete and query the information in the database through the corresponding module and print the dormitory basic dosage information. They may update, delete administrator information who use the system and buy electricity application for users, such the system management function is a lot. Because this system has high transparency, so users can use associated dormitory electricity payment information to query, because the dormitory groups mainly concentrate in the university campus, the dormitory management design and implementation designs consideration of the user object for the campus of the University students. Through the application of the system, school can enhance the information management of the dormitory electricity use, reduce the burden on administrators, and improve work efficiency. We can see, the one who has mastered the knowledge that is large volume, information that is large volume, the high information processing speed, whose efficiency is high, who can be in petition remain invincible in.
