【正文】 brary technology will C / C + + or assembly language programs to Visual Basic 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 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, 共 13 頁 第 1 頁 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 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)庫系統(tǒng)的開發(fā)， Visual Basic 是一個非常理想選擇。 總的來說， Visual Basic 具 有以下特點： 可視化編程： 用傳統(tǒng)程序設(shè)計語言設(shè)計程序時，都是通過編寫程序代碼來設(shè)計用戶界面，在設(shè)計過程中看不到界面的實際顯示效果，必須編譯后運行程序才能觀察。只需要按設(shè)計要求的屏幕布局，用系統(tǒng)提供的工具，在屏幕上畫出各種“部件”，即圖形對象，并設(shè)置這些圖形對 象的屬性。在設(shè)計對象時，不必編寫建立和描述每個對象的程序代碼，而是用工具畫在界面上， Visual Basic 自動生成對象的程序代碼并封裝起來。 Visual Basic 是解釋型語言，在輸入代碼的同時，解釋系統(tǒng)將高級語言分解翻譯成計算機可以識別的機器指令，并判斷每個語句的語法錯誤。例如，命令按鈕是一個對象，當用戶單擊該按鈕時，將產(chǎn)生一個“單擊” (CLICK)事件，而在產(chǎn)生該事件時將執(zhí)行一段程序，用來實現(xiàn)指定的操作。同時， Visual Basic 還能直接編輯和訪問其他外部數(shù)據(jù)庫，如 DBASE， FoxPro， Paradox 等，這些數(shù)據(jù)庫格式都可以用 Visual Basic 編輯和處理。當原始數(shù)據(jù)變化時，可以自動更新鏈接的數(shù)據(jù)。利用 OLE 技術(shù)，可以方便地建立復合式文檔 (pound document)，這種文檔由來自多個不同應用程序的 共 13 頁 第 9 頁 對象組成，文檔中的每個對象都與原來的應用程序相聯(lián)系，并可執(zhí)行與原來應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 正式開發(fā)管理信息系統(tǒng)之前進行調(diào)研是非常必要的，其必要性主要表現(xiàn)在以下幾個方面。 （ 3）企業(yè)的現(xiàn)行系統(tǒng)可能是手工系統(tǒng)，也可能是使用和計算機的系統(tǒng)，無論是何種情況，都要詳細地調(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)計出一個合理的、好的新系統(tǒng)邏輯模型，為新系統(tǒng)的設(shè)計工作打好基礎(chǔ)，保證整個系統(tǒng)開發(fā)的質(zhì)量。 (1)可行性分析階段的主要工作 包括以下幾個方面： 共 13 頁 第 10 頁 ①新系統(tǒng)目標可行性分析： 分析新系統(tǒng)的目標是否符合企業(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)導是否具有現(xiàn)代化的管理意識和管理水平。 （ 2）硬件資源： 開發(fā)管理信息
