【正文】 密級： 工程碩士專業(yè)學位論文（設(shè)計） 題 目 基于 B/S 架構(gòu)的企業(yè)采購管理系統(tǒng)的設(shè)計與實現(xiàn) 基于 B/S 架構(gòu) 的企業(yè)采購 管理系統(tǒng)的設(shè)計與實現(xiàn) 當今， 伴隨著信息科學計算機技術(shù)的應用與發(fā)展， 推動了經(jīng)濟的高速發(fā)展，同時計算機技術(shù)與網(wǎng)絡(luò)技術(shù)的發(fā)展與應用變得越來越普及 。 企業(yè)自身的建設(shè)發(fā)展需要轉(zhuǎn)變傳統(tǒng)的發(fā)展方式，而 信息系統(tǒng)與網(wǎng)絡(luò)是重中之重。 目前國內(nèi)外各大企業(yè)已經(jīng)基本上淘汰了傳統(tǒng)的線下及紙質(zhì)的企業(yè)采購，取而代之的是更加方便快捷的計算機產(chǎn)品的使用，這使企業(yè)的管理與經(jīng)營變得更加高效、簡潔。這不僅節(jié)省了企業(yè)的管理成本與時間精力，更可以讓企業(yè)在科學信息化的浪潮中持續(xù)發(fā)展。 企業(yè)信息化系統(tǒng)中的重要組成部分就是采購管理， 采購管理系統(tǒng)的使用為企業(yè)辦公提供了一個新的平臺，降低了企業(yè)辦公成本，提高了企業(yè)辦公的效率。企業(yè)采購管理系統(tǒng)管理者負責整個企業(yè)采購系統(tǒng)的管理操作，使傳統(tǒng)的數(shù)據(jù)記錄及交易信息能夠通過 計算機快速的 記錄下來 。 本文著重闡述 了 企業(yè)采購管理系統(tǒng) 的整體開發(fā)過程。并對開發(fā)需要的相關(guān)技術(shù)，包括開發(fā)環(huán)境、開發(fā)工具的介紹，并對于程序設(shè)計的思想和流程進行了全面的闡述，同時在數(shù)據(jù)庫的構(gòu)造時對各表之間的具體關(guān)系及表內(nèi)字段的完整性、約束性也做出了具體的設(shè)計說明，最終保證系統(tǒng)能夠正確的運行。同時用簡單的功能模塊圖來清晰的表明系統(tǒng)中的設(shè)計思路和系統(tǒng)運行的整個流程。 本系統(tǒng)具體包括計劃采購物品、采購物品報價、合同采購信息、合同采購審核、入庫登記信息、退貨登記信息、財務統(tǒng)計信息、用戶信息列表。 根據(jù)實際需求， 企業(yè)采購管理系統(tǒng) 采用 Browser/Server 體系結(jié)構(gòu)進行設(shè)計，開發(fā)技術(shù)使用了目前較流行的 技術(shù)，腳本語言使用 C，使用三層架構(gòu)技術(shù)。在設(shè)計過程中，前臺的開發(fā)工具使用微軟公司的 Microsoft Visual Studio 20xx，后臺數(shù)據(jù)庫采用 Microsoft SQL Server 20xx。按照軟件工程的面向結(jié)構(gòu)的設(shè)計方法，在設(shè)計的過程中，經(jīng)過了需求分析、總體設(shè)計、詳細設(shè)計、系統(tǒng)測 試等過程，具體的分析了系統(tǒng)中的各個功能模塊的具體需求，設(shè)計了 企業(yè)采購管理系統(tǒng) 的整體功能結(jié)構(gòu)，通過 SQL Server 完成了數(shù)據(jù)庫的結(jié)構(gòu)分析與設(shè)計，最后對系 統(tǒng)的各個具體的模塊進行界面設(shè)計、編碼設(shè)計及系統(tǒng)測試，最終實現(xiàn)基于 B/S 架構(gòu)的企業(yè)采購管理系統(tǒng)。 本論文首先介紹了在信息系統(tǒng)的支持下采購管理系統(tǒng)相關(guān)的發(fā)展背景、開發(fā)的目的、國內(nèi)外研究現(xiàn)狀。通過相關(guān)技術(shù)介紹和應用，然后通過標準的開發(fā)流程，完成了企業(yè)采購管理系統(tǒng)的系統(tǒng)分析、系統(tǒng)設(shè)計與功能的實現(xiàn)。 關(guān)鍵詞： 采購 系統(tǒng)； 企業(yè)管理 ； 三層架構(gòu)， B/S 架構(gòu) ； The design and implementation of the Enterprise Procurement Management System based on B/S structure Software Engineering Graduate Student： Adviser: Today, along with the application and development of information science and puter technology to promote the rapid economic development, while the development and application of puter technology and work technology is being increasingly popular. Construction and development of their own need to change the traditional mode of development, and information systems and works is a top priority. Currently the major domestic and foreign enterprises have basically eliminated the traditional line and paperbased corporate procurement, replaced by a more convenient and efficient use of puter products, which makes business management and business bee more efficient and concise. This not only saves the pany39。s administrative costs and time and energy, but also allows panies to scientific information in the wave of sustainable development. Enterprise information system is an important part of procurement management, procurement management system for the use of corporate office provides a new platform, reducing the corporate office costs and improve the efficiency of corporate office. Corporate procurement management system administrators responsible for the entire enterprise procurement system management operations, the traditional data logging and transaction information can be quickly recorded by the puter. This paper focuses on the overall development process of enterprise purchasing management system. Development needs and related technologies, including the development environment, development tools, presentation and design ideas for the program and a prehensive exposition of the process, but at the time of construction of the database table and the specific relationship between the tables field integrity constraint is also made specific description of the design, and ultimately ensure that the system is running correctly. At the same time with a simple functional block diagram to clearly show the entire process system design ideas and system operation. The system includes plans to purchase specific items, purchasing goods offer, contract procurement information, contract procurement auditing, warehousing registration information, return the registration information, financial statistics, user information list. According to the actual needs of corporate procurement management system using Browser / Server architecture, design, development techniques using technology is currently more popular scripting languages using C , using a threetier architecture technology. During the design process, the front desk to use Microsoft39。s development tools Microsoft Visual Studio 20xx, background database using Microsoft SQL Server 20xx. By design methods for structural engineering software in the design process, after a needs analysis, design, detailed design, system testing process, a detailed analysis of the specific needs of each module in the system, the design of corporate procurement overall functional structure of the management system, SQL Server acplished through structural analysis and design of the database, and finally each specific modules of the system interface design, code design and system testing, and ultimately based on B / S structure of corporate procurement management system. This paper introduces the related procurement management system development background in support of information systems under development purposes, research status. Through the introduction and application of relevant technologies, and then through the standard development process, pleted a systematic analysis of corporate procurement management, system design and implementation functions. Key words： Procurement system。Enterprise management。Three layer architecture, B/S architecture。 四川大學工程碩士學位論文 基于 B/S架構(gòu)的企業(yè)采購管理系統(tǒng)的設(shè)計與實現(xiàn) I 目 錄 THE DESIGN AND IMPLEMENTATION OF THE ENTERPRIS E PROCUREMENT MANAGEMENT S YSTEM BAS ED ON B/S STRUCTURE ................................................................. 4 第一章 緒 論 ........................................................................................................................................................ 1 研究背景 .................................................................................................................................................... 1 研究目的及意義 ..................
