摘 要
隨著網絡的逐步普及，網上購物已經逐漸成為一種新的購物方式，并受到大家的認可。產品報價系統正是網上購物系統的一種，將產品報價與在線購物有機的結合在一起，能為用戶提供一種全方位、高效率的服務。
經過對系統需求及功能分析，決定采用.NET平臺，利用SQL Server 2000數據庫技術并結合當今幾大主流購物網站實際狀況建立一個全新的報價系統。該系統包括兩大功能模塊：管理員模塊、用戶模塊，實現了管理員對用戶、商品、訂單的全面管理，以及用戶對商品的查詢、訂購功能。
本文首先簡要闡述了產品報價系統的開發背景及意義，其次著重闡述了采用.NET技術對該系統的開發實現過程，從系統分析、數據庫設計、系統功能設計等環節進行詳細描述。在開發過程中運用到了一些前端控件來控制輸入信息，對輸入信息進行驗證，采用ADO.NET技術連接數據庫。在系統分析中先后用數據流程圖、系統的功能結構圖分析了系統所需的各種數據，詳細的展現了系統的各個功能模塊并給出了主要功能運行界面圖，并通過系統測試，達到了預期的效果。

Design of Product Quotation System Based on.NET
Abstract
Along with the development of internet, on-line shopping gradually becomes a new way of shopping and is accepted by more and more people. The products quotation system is one type of the on-line shopping system which combines products quotation with the on-line shopping, providing users an all-directional and high-effective service.
The products quotation system which is a new one was based on the platform of NET, using techniques of SQL Server 2000 database and combining the practical conditions of the present main shopping websites. It includes two functional modules: manager module and user module, which realize the whole controlling over users, goods and orders and the functions of checking goods information and ordering them of users.
Firstly, this paper defines the background and meanings of its development. And then it focuses on the process of realization through .NET technology, analyzing the processes of system, database design and functional design of the system in detail. During the development, it uses some front components to control the input information and check the information. It connects database through ADO.NET technology. During the analysis, it analyzes various data, laying out each functional module in detail and giving surface charts actives of main functions by data flow chart and systematical structure chart. Finally it achieves the due goal through the system checking.
