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)主要實現(xiàn)對貨品信息和采購信息的管理, 以采購管理系統(tǒng)為模型,以 單 據(jù)查詢、采購管理、基本信息管理以及系統(tǒng)維護等為主要功能。幫助軸承企業(yè)采購部門全面實現(xiàn)電子化、自動化、標準化的現(xiàn)代化先進管理模式。 畢業(yè)設計(論文) I 采購管理 摘 要 本系統(tǒng)是基于為軸承企業(yè)采購部門開發(fā)的系統(tǒng)。 課題主要采用自上而下的結構化程序設計方法與面向對象方法相結合的方法, 致力于達到標準的現(xiàn)代化物流管理要求。 該系統(tǒng)使用 編程語言進行界面設計和代碼設計,主要使用 中的 來對數(shù)據(jù)庫進行各種操作,數(shù)據(jù)庫設計使用 SQL Server 2021 創(chuàng)建 。 正文分八章:第一章是緒論,主要涉及系統(tǒng)的開發(fā)背景和開發(fā)目的;第二章至第七章講述軟件生命周期各階段的任務、過程、結構化方法和工具;第八章是對整個文章的總結。 query。 采購管理相應界面 ........................................... 錯誤 !未定義書簽。 模塊的設計 ............................................................................................... 32 程序流程圖 ............................................................................................... 38 第 6 章 系統(tǒng)測試 ................................................................................................... 40 測試的目的 ............................................................................................... 40 測試準則 ................................................................................................... 41 測試方法 ................................................................................................... 41 安順軸承采購管理系統(tǒng)的測試步驟 ....................................................... 41 模塊測試 ......................................................................................... 42 子系統(tǒng)測試 ..................................................................................... 42 系統(tǒng)測試 ......................................................................................... 42 驗收測試 ......................................................................................... 42 安順軸承采購管理系統(tǒng)的單元測試 ....................................................... 42 測試重點 ......................................................................................... 4
