This article discusses the development of the system by bining the uptodown method of structure program design and objectoriented method， trying to meet the requirement of management of standard and modern physical distribution, and enable the purchasing department of axletree enterprises electronic, automatic, standard and modern management mode. The system adopted the Visual language to develop the UI and main codes. technology was used to plete various database operations. The database system is SQL Server 2021. This system mainly implements the function of management of goods information and purchase information， drawing up the management system of purchase as the mode, with the function such as: query of bill, purchasing management, basic information management and system maintenance. The paper enpasses eight chapters: Chapter One introduces the background and objective of the development of the system. Chapter Two to Chapter Seven focus on the task, process, structure method and tools at every stage of the software development life cycle. Chapter Eight is the conclusion of the whole paper. Keywords: purchase。 該系統(tǒng)主要實(shí)現(xiàn)對(duì)貨品信息和采購(gòu)信息的管理， 以采購(gòu)管理系統(tǒng)為模型，以 單 據(jù)查詢(xún)、采購(gòu)管理、基本信息管理以及系統(tǒng)維護(hù)等為主要功能。幫助軸承企業(yè)采購(gòu)部門(mén)全面實(shí)現(xiàn)電子化、自動(dòng)化、標(biāo)準(zhǔn)化的現(xiàn)代化先進(jìn)管理模式。 畢業(yè)設(shè)計(jì)（論文） I 采購(gòu)管理 摘 要 本系統(tǒng)是基于為軸承企業(yè)采購(gòu)部門(mén)開(kāi)發(fā)的系統(tǒng)。 課題主要采用自上而下的結(jié)構(gòu)化程序設(shè)計(jì)方法與面向?qū)ο蠓椒ㄏ嘟Y(jié)合的方法， 致力于達(dá)到標(biāo)準(zhǔn)的現(xiàn)代化物流管理要求。 該系統(tǒng)使用 編程語(yǔ)言進(jìn)行界面設(shè)計(jì)和代碼設(shè)計(jì)，主要使用 中的 來(lái)對(duì)數(shù)據(jù)庫(kù)進(jìn)行各種操作，數(shù)據(jù)庫(kù)設(shè)計(jì)使用 SQL Server 2021 創(chuàng)建 。 正文分八章：第一章是緒論，主要涉及系統(tǒng)的開(kāi)發(fā)背景和開(kāi)發(fā)目的；第二章至第七章講述軟件生命周期各階段的任務(wù)、過(guò)程、結(jié)構(gòu)化方法和工具；第八章是對(duì)整個(gè)文章的總結(jié)。 query。 采購(gòu)管理相應(yīng)界面 ........................................... 錯(cuò)誤 !未定義書(shū)簽。 模塊的設(shè)計(jì) ............................................................................................... 32 程序流程圖 ............................................................................................... 38 第 6 章 系統(tǒng)測(cè)試 ................................................................................................... 40 測(cè)試的目的 ............................................................................................... 40 測(cè)試準(zhǔn)則 ................................................................................................... 41 測(cè)試方法 ................................................................................................... 41 安順軸承采購(gòu)管理系統(tǒng)的測(cè)試步驟 ....................................................... 41 模塊測(cè)試 ......................................................................................... 42 子系統(tǒng)測(cè)試 ..................................................................................... 42 系統(tǒng)測(cè)試 ......................................................................................... 42 驗(yàn)收測(cè)試 ......................................................................................... 42 安順軸承采購(gòu)管理系統(tǒng)的單元測(cè)試 ....................................................... 42 測(cè)試重點(diǎn) ......................................................................................... 42
