asic applications, you can call the same function as the internal call functions written in other languages. In addition, the dynamic link library, you can call the Windows application program interface (API) function has the function to achieve SDK. systems research and feasibility analysis Research Before the formal development of management information system is necessary for research, the need for mainly the following aspects. (1) to the user39。 and some emphasis on the visual application development tools to bring convenience and efficiency high, each with its own advantages and characteristics, but also to meet the needs of different users. However, the language of the flexibility and convenience tools are inextricably linked, and only a convenient tool, but did not support the language of flexibility, many specialized processing actions will need to spend several times the effort to deal with, so the efficiency of the original advertisedloss of a role in improving the advantage。 inparable advantage of the puter to retrieve managementrapid, easy to find, high reliability, large memory capacity, security and good, long life and low cost. These advantages can greatly improve the efficiency of personnel management, but also corporate scientific and standardized management, an important condition for integration with the world. Different panies have different human resources management system, which determines the different panies need different personnel management system. choice of development tools Now, the market can buy a lot of application development products, popular, and dozens. Currently the most popular in our market, the most used, most advanced development tools can be used as enterpriselevel products: Microsoft39。s Visual Basic Microsoft39。 the contrary, if the language only emphasizes the flexibility of process continued, but no convenient tool for coordination will make some very simple interface, even if the deal moves, programmers will be a serious waste of valuable time. As the database system development, Visual Basic is an ideal choice. MIS database is 共 13 頁(yè) 第 2 頁(yè) an important enabling technology in the MIS development process, how to choose the database management is an important issue, at present, the database more products, each product has its own characteristics and scope, therefore, the choice of database should consider the characteristics of database applications and application, the system39。s request to conduct a feasibility analysis of the survey results confirm the feasibility of system development. (2) The staff of the new system not all systems researchers, some people process data for its function and no clear understanding of the method. They only work according 共 13 頁(yè) 第 5 頁(yè) to their business needs requests, system developers to conduct a detailed survey and analysis to confirm the user39。 the new system the number and level of developers, namely, human resources。 ② build system choice。 ⑥ application package choice. In the development of this system before, with the center39。不同的企業(yè)具有不同的人事管理制度,這就決定了不同的企業(yè)需要不同的人事管理系統(tǒng)。 作為數(shù)據(jù)庫(kù)系統(tǒng)的開(kāi)發(fā), Visual Basic 是一個(gè)非常理想選擇。 總的來(lái)說(shuō), Visual Basic 具有以下特點(diǎn): 可視化編程: 用傳統(tǒng)程序設(shè)計(jì)語(yǔ)言設(shè)計(jì)程序時(shí),都是通過(guò)編寫(xiě)程序代碼來(lái)設(shè)計(jì)用戶(hù)界面,在設(shè)計(jì)過(guò)程中看不到界面的實(shí)際顯示效果,必須編譯后運(yùn)行程序才能觀察。只需要按設(shè)計(jì)要求的屏幕布局,用 系統(tǒng)提供的工具,在屏幕上畫(huà)出各種“部件”,即圖形對(duì)象,并設(shè)置這些圖形對(duì)象的屬性。在設(shè)計(jì)對(duì)象時(shí),不必編寫(xiě)建立和描述每個(gè)對(duì)象的程序代碼,而是用工具畫(huà)在界面上, Visual Basic 自動(dòng)生成對(duì)象的程序代碼并封裝起來(lái)。 Visual Basic 是解釋型語(yǔ)言,在輸入代碼的同時(shí),解釋系統(tǒng)將高級(jí)語(yǔ)言分解翻譯成計(jì)算機(jī)可以識(shí)別的機(jī)器指令,并判斷每個(gè)語(yǔ)句的語(yǔ)法錯(cuò)誤。例如,命令按鈕是一個(gè)對(duì)象,當(dāng)用戶(hù)單擊該按鈕時(shí),將產(chǎn)生一個(gè)“單擊” (CLICK)事件,而在產(chǎn)生該事件時(shí)將執(zhí)行一段程序,用來(lái)實(shí)現(xiàn)指定的操作。同時(shí), Visual Basic 還能直接編輯和訪問(wèn)其他外部數(shù)據(jù)庫(kù),如 DBASE, FoxPro, Paradox 等,這些數(shù)據(jù)庫(kù)格式都可以用 Visual Basic 編輯和處理。當(dāng)原始數(shù)據(jù)變化時(shí),可以自動(dòng)更新鏈接的數(shù)據(jù)。利用 OLE 技術(shù),可以方便地建立復(fù)合式文檔 (pound document),這種文檔由來(lái)自多個(gè)不同應(yīng)用程序的 共 13 頁(yè) 第 11 頁(yè) 對(duì)象組成,文檔中的每個(gè)對(duì)象都與原來(lái)的應(yīng)用程序相聯(lián)系,并可執(zhí)行與原來(lái)應(yīng)用程序完全相同的操作。 系統(tǒng)調(diào)研及可行性分析 3. 1 系統(tǒng)調(diào)研 正式開(kāi)發(fā)管理信息系統(tǒng)之前進(jìn)行調(diào)研是非常必要的,其必要性主要表現(xiàn)在以下幾個(gè)方面。 ( 3)企業(yè)的現(xiàn)行系統(tǒng)可能是手工系統(tǒng),也可能是使用和計(jì)算機(jī)的系統(tǒng),無(wú)論是何種情況,都要詳細(xì)地調(diào)查現(xiàn)行系統(tǒng)中信息處理的具體情況,系統(tǒng)內(nèi)部功能結(jié)構(gòu),以便設(shè)計(jì)出一個(gè)合理的、好的新系統(tǒng)邏輯模型,為新系統(tǒng)的設(shè)計(jì)工作打好基礎(chǔ),保證整個(gè)系統(tǒng)開(kāi)發(fā)的質(zhì)量。 (1)可行性分析階段的主要工作 包括以下幾個(gè)方面: 共 13 頁(yè) 第 12 頁(yè) ①新系統(tǒng)目標(biāo)可行性分析: 分析新系統(tǒng)的目標(biāo)是否符合企業(yè)的現(xiàn)狀和發(fā)展的需要。 ⑤ 管理可行性分析: 管理可行性分析主要是分析企業(yè)現(xiàn)行的管理體制和企業(yè)領(lǐng)導(dǎo)是否具有現(xiàn)代化的管理意識(shí)和管理水平。 ( 2)硬件資源: 開(kāi)發(fā)管理信息系統(tǒng)所需的硬件資源包含以下兩個(gè)方面: 系統(tǒng)開(kāi)發(fā)人員在管理信息系統(tǒng)的開(kāi)發(fā)過(guò)程 中所需要的計(jì)算機(jī)設(shè)備及其有關(guān)的外部設(shè)備;管理信息系統(tǒng)開(kāi)發(fā)成功投入使用后,使用單位所應(yīng)具備的計(jì)算機(jī)設(shè)備及其有關(guān)的外圍設(shè)備。
