❺ 用数据库做一个小型设备管理系统
课题1. 《设备管理信息系统》包括的实体类型有：n 固定资产（资产编号，资产名称，型号规格，计量单位，价值，制造厂，出厂日期）n 部门（部门编号，部门名称，负责人）n 折旧单（折旧单编号，年折旧率，年折旧额，开始使用日期，全部使用年限，已使用年数，尚可使用年限）n 大修理单（修理单编号，修理日期，修理时限，修理费用，经手人）n 内部转移单（转移单编号，转移日期，转出部门，转入部门），即该设备从一个部门调拨到另一个部门n 报废单（报废单编号，报废日期，经手人），指该设备已经到了使用年限，扔到废品仓库里n 清理单（清理单编号，资产原值，累计折旧金额，清理金额），从废品仓库里清理掉。n 《设备管理信息系统》包括的具体操作：n 自行补充实体之间的联系n 输入数据，每个表不少于10行数据，数据必须是有意义的n 实现设备报废过程n 实现设备的内部转移n 统计固定资产的已进行的大修费用n 列出两个基本表的插入、更新和删除记录的操作（各举1例）n 自行补充8至10个SQL操作，如信息分院的固定资产价值，列出所有的“计算机”设备清单等等
❻ 设计一个数据库系统要怎么设计
数据库系统只有一种语言,这种语言叫SQL.
你可以使用PowerDesigner来进行数据库PDM和CDM设计,支持当前各种主流的数据库数据格式.
❼ 小型数据库管理系统的设计
小规模的数据库关系系统
❽ 如何用prontpage和SQL设计一个小型的数据库系统(学生综合测评排名系统)
首先在SQL中利用企业管理器或向导建立一个数据库，命名为学生管理系统， 启动SQL Sever服务，运行企业管理器，单击要创建数据库的服务器左边的加号图标，展开树形目录，在“数据库”节点上右击鼠标，在弹出的快捷菜单中选则“新建数据库”命令，然后按照提示一步步建立数据库，不再详细叙述。 假设学生管理系统下有三个表，分别为学生表、课程表、修课表，表的结构
