【正文】 I 摘 要 本文詳細敘述了超市管理系統(tǒng)的設計與實現過程。在整個開發(fā)過程中，對超市各部門工作業(yè)務流程以及商品的進銷存等操作進行了詳細的調研，并根據顧客、超市員工以及經理的需求制定了一套具體的解決方案。 本系統(tǒng)是基于 C＃的超市管理系統(tǒng)，采用 Visual Studio 2021 及 SQL Server 2021 作為開發(fā)工具。本系統(tǒng)是 C/S（ 客戶端 /服務器 ） 結構的超市管理系統(tǒng)。其中包括前臺（客戶端）以及后臺（服務器）兩部分，前臺的主要功能是：員工登錄 、 商品銷售。后臺的主要功能是：進貨管理 、 庫存管理 、 銷售管理 、 會員管理 、 職 工管理 、 報表管理 、 后臺管理 、 系統(tǒng)設置 、系統(tǒng) 幫助等。 本系統(tǒng)功能貼近實際 、 內容完善 、 運行穩(wěn)定。使用本系統(tǒng)可以迅速提升超市的管理水平，為降低經營成本、提高效益、增強超市擴張力提供了有效的技術保障。 關鍵詞： 商品價簽；條碼；在線升級 II Abstract This article described the process of the design and implementation about Supper Market Management System. Throughout the development process, had done a detailed investigation about the Supermarket different departments to business process and purchase of goods, sale, storage, and so on. According to the customers, employees and store managers’ needs to deve lop a set of specific solutions. This Supermarket Management System is based on the C .Using Visual Studio 2021 an d SQL Server 2021 as a development supermarket management system taked C/S ( Client / Server) as a consists of front(Client) and background (Server)of two parts. The main functions of the front are: employees log on, the sale of goods. The main functions of the background are: purchase management, storage management, sales management, associ ator management, staff management, report Management, background Management, System Settings, Help and so on. This system function es close actual, contents refinement, stability of the running. To use the system can elevate the level of supermarket management. In order to reduce operating costs, raise efficiency, enhance the expansion of supermarket power, it provides effective technical support.
