【正文】 s or business person can not see all the information and customer information, and information makes the results of dispersion can not maintain the consistency and integrity, With the continuous improvement of science and technology, puter science and the maturing of its powerful features have been a profound understanding of people. It has access to all areas of human society and play an increasingly important role. As part of the puter, the use of puter information on the automobile sales management, management can not be pared with the manual of the advantages of. For example, the search quickly and find the convenience, high reliability and large storage capacity, the confidentiality of a good, long life and low cost. These advantages can greatly improve the efficiency of the management of car sales, but also allows panies to carry out scientific and standardized management, and this is an important condition for the rest of the world, And the system is calculated using the advanced approach, so that the system has a very powerful data processing and statistical functions integrated query, greatly reducing the human resources, increase the accuracy of information analysis. As a sales management system that can query for goods, browsing, storage out of the Treasury, to improve efficiency are important. The system also has good flexibility and openness. Users can easily manage the project, change the current management of the content.Keywords database；sales management；basic information； permissions目錄摘要 IAbstract II第1章 緒論 1 系統(tǒng)開發(fā)背景 1 系統(tǒng)開發(fā)環(huán)境 1第2章 可行性分析 2 技術(shù)可行性 2 經(jīng)濟(jì)可行性 2 操作可行性 2 法律可行性 2第3章 需求分析 4 業(yè)務(wù)流程 4 車輛入庫 4 車輛銷售 4 車輛查詢 5 車輛匯總 5 車輛系統(tǒng)管理 5 需求規(guī)范 5 產(chǎn)品背景 5 產(chǎn)品概述 5 功能需求 6 系統(tǒng)邏輯模型（結(jié)構(gòu)化的方法） 6 系統(tǒng)邏輯模型（面向?qū)ο蠓椒ǎ?8 數(shù)據(jù)字典 10 數(shù)據(jù)元素定義 10 數(shù)據(jù)流的定義 10 數(shù)據(jù)存儲定義 11 數(shù)據(jù)處理定義 12第4章 概要設(shè)計(jì) 15 系統(tǒng)運(yùn)行總體流程 15 目標(biāo)系統(tǒng)體系結(jié)構(gòu) 16 進(jìn)銷存管理系統(tǒng)軟件結(jié)構(gòu)圖 16 “系統(tǒng)管理”模塊結(jié)構(gòu)圖 17 “車輛匯總”模塊結(jié)構(gòu)圖 17 各實(shí)體ER圖 18 入庫管理實(shí)體ER圖 18 銷售管理實(shí)體ER圖 18 汽車資料實(shí)體ER圖 19第5章 數(shù)據(jù)庫設(shè)計(jì) 20第6章 詳細(xì)設(shè)計(jì) 25 25 模塊設(shè)計(jì) 25 登錄窗口設(shè)計(jì) 25 主窗口設(shè)計(jì) 29 添加新用戶窗口設(shè)計(jì) 33 修改密碼窗口設(shè)計(jì) 37 查詢輸出窗口設(shè)計(jì) 40第7章 軟件測試 44 登錄系統(tǒng)模塊測試用例 44 匯總模塊測試用例 46結(jié)論 47致謝 48參考文獻(xiàn) 49附錄A 50附錄B 55security rope fence.
