| 摘要：此次课题经过了需求的分析，结合当前市场的需求和社会的发展状况，了解到了企业仓储管理系统的核心在于管理货品的出库入库的的过程，相互构成了一个完整的物流系统。在程序中涉及到了供应商、客户、仓库增删改查的功能模块，通过订单和销售单将它们的关系联系起来。具体来说就是企业向供应商发出订货申请，生成了订单，订单确认后商品入库存放，企业再向客户销售商品，生成销售单，销售单确认后商品调拨出库发往客户。根据这一核心的入库出库模块进一步将需求细化到各个环节，仓储的管理功能主要体现在对库存商品信息的添加、删除、修改、删除等操作。之后经过了较为精细严谨的数据库设计（运用到了较多的外键约束）使得为之构建了相对准确、匹配的数据库系统，且保证了数据的完整性和严密性，最终共同完成整个仓库系统的正常运转。 毕业论文关键词：仓储管理；物流系统；增删改查；24186 Enterprise Warehouse Management System Development Abstract : After the analysis of the subject demand, combined with the current market demand and the development of society, learn the core enterprise warehouse management system is a process management library storage of goods , and mutual constitute a complete logistics system . Involved in the program to suppliers, customers , warehouses CRUD functionality module, through orders and sales orders linked to their relationship . Specifically, enterprise applications issued orders to suppliers , generate the order after order confirmation merchandise warehousing storage, enterprise customers again selling products, generating sales orders, sales orders after confirmation of goods sent to the customer for the library . According to the core of the storage needs of the library module further refinement to all aspects of warehouse management functionality is mainly reflected in the inventory of goods information to add , delete , modify, or delete operation . After a more refined rigorous database design ( applied to the more foreign key constraint ) makes whom constructed relatively accurate matching database system, and to ensure the integrity and rigor , to complete the final common data warehouse system normal operation . Keywords: Warehouse management; logistics systems; CRUD; 目录 摘要 i Abstract i 目录 ii 1 绪论 1 1.1 课题分析 1 1.1.1 课题的目的和意义 1 1.1.2 国内外研究现状 1 1.1.3 水平和发展趋势 2 2 分析 3 2.1 可行性分析 3 2.2 需求分析 3 2.2.1 系统功能说明 3 2.2.2 数据流图DFD 5 2.2.3 数据字典DD 6 2.2.4 数据结构 9 2.2.5 处理过程 10 3 设计 11 3.1 模块详细设计 11 3.2 数据库设计 11 3.2.1 E-R图 11 3.2.2 关系模式 15 3.2.3 建表 15 3.2.4 关系图 18 4 实现 19 4.1 各功能模块实现 19 4.2 测试 26 4.2.1 供应商模块 26 (责任编辑：qin) |
