数据库课程设计(改)

1、东 莞 理 工 学 院课程设计课程名称： 数据库系统原理 设计题目： 库存物资管理 院系名称 计算机学院 班 级 软件工程（2）班 学生姓名 潘东扬 学号 1 组 员叶碧怡、李斯斯、黎小浪、陈开贵、冯锡恩、梁志飞、袁杰生、廖裕森、刘浩锋、黄力、黎炽培、陈耀新 指导教师 欧阳骥 时 间 一周 一、 进行需求分析，编写数据字典。1、系统功能要求设计 有一个存放商品的仓库，每天都有商品出库和入库。 每种商品都有商品编号、商品名称、生产厂家、型号、规格等。 入库时必须填写入库单据，单据包括商品名称、生产厂家、型号、规格、入库数量、入库日期、入库仓库号、入库仓库名称、送货人姓名。 出库时必须填写出库单据

2、，单据包括仓库号、仓库名称、商品编号、商品名称、型号、规格、出库数量、出库日期、提货人姓名。 设置商品库存台帐，商品库存台帐是对仓库中目前库存的所有商品的明细记录，商品库存台帐包括商品编号、商品名称、型号、规格、库存数量、库存日期。每当有商品入库或商品出库时都应该自动修改该台帐，最后一次修改的是现在的库存情况。 商品的入库和出库过程通过库存台帐更加清晰条理地显示出仓库中商品的库存数量和库存日期等信息，容易对库存内的商品信息进行查询，增加，修改，删除等操作。 该仓库的商品型号统一为DA01-DA99格式，规格为CX100-CX199格式主要功能： 商品管理： 增加商品：修改商品，删除商品，浏览商

3、品增加商品：实现增加商品的详细资料的功能修改商品：实现修改商品资料的功能删除商品：实现删除该商品的所有资料的功能浏览商品：实现浏览所有商品的功能 库存管理： 实现商品的入库，在商品入库时通过触发器或存储过程同时完成商品库存台帐的更新。实现商品的出库，在商品出库时通过触发器或存储过程同时完成商品库存台帐的更新。实现按商品名称查询商品的入库情况及目前的库存量。实现按入库日期查询商品的入库情况及目前的库存量。实现按商品名称查询商品的出库情况及目前的库存量。实现按出库日期查询商品的出库情况及目前的库存量。按时间段查询商品库存情况。实现分别按年、季度和月对入库商品数量的统计。实现分别按年、季度和月对出库

4、商品数量的统计。2、系统模块设计库存物资管理大体可以分为以下3大模块，如下图所示:首先是商品入库模块，该模块主要就是描述把采购回来的商品，分类别的放置到指定的仓库中去，然后是商品出库模块，该模块主要描述从指定的仓库中拿出商品；最后时库存模块，这个模块主要是记录商品的库存数量变化。库存物资管理商 品 入 库 模 块商 品 出 库 模 块商 品 库 存 模 块3、数据字典表表名中文名Ware商品Depot仓库Stock库存Stocking入库Outbound出库商品Ware字段名数据类型是否可以为空Is PKIs FK中文名WNochar(10)NOT NULLYesNo商品编号WNamevarc
