java课程设计报告题 目 华联超市进销管理系统 一.需求分析企业进销存管理系统的主要工作，是对企业的进货、销售和库存以信息化的方式进行管理，最大限度的减少各个环境中可能出现的错误，有效减少盲目采购，降低采购成本、合理控制库存、减少资金占用并提高市场灵敏度，使企业能够合理安排进、销、存的每个关键步骤，替身企业市场竞争力。针对经营管理中存在的问题，兰州华联超市对产品的进销存合理化提出了更高的要求。 通过实际调查，要求企业进销存管理系统具有以下功能。 界面设计美观大方，方便、快捷、操作灵活。实现强大的进销存管理，包括基本信息、进货、销售和库存管理。能够在不同的操作系统下运行，不局限于特定的平台。提供数据库备份与恢复功能。提供库存盘点功能。提供技术支持的联系方式，可以使用邮件进行沟通，或者直接连接到技术网站。二.分析与设计：(1)功能模块划分:本进销存管理系统划分为六个模块，分别为系统登陆模块，系统主窗体设计模块，进货单模块，销售单模块，库存盘点模块和数据库备份与恢复模块，(2)数据库结构描述:企业进销存管理系统需要使用数据库存储和管理进销存过程中的所有信息，本企业进销存管理系统使用sql server 2000数据库系统作为后台数据库，数据库名称为db_database28。其中包含了14张数据表两个视图。以下是系统主要涉及的六个数据库表：1供应商信息表：主要用于存储供应商详细信息，其结构如下表所示：tb_gysinfo供应商信息表字段名称数据类型字段大小是否主键说明idvarchar32主键供应商编号namevarchar50供应商名称jcvarchar20供应商简称addressvarchar100供应商地址bianmavarchar10邮政编码telvarchar15电 话faxvarchar15传 真lianvarchar8联 系 人ltelvarchar15联系电话yhvarchar50开户银行mailvarchar50电子信箱2.商品信息表：主要用于存储商品详细信息，其结构如下表所示;
