3、库实例数据库系统数据库部署环境数据库设计工具数据库存放位置说明3 数据库的命名规则数据库名称：时代集团的英文名称time-group表名：英文（表的用途）+下划线+英文字段名：相关属性的英文名4 逻辑设计提示：数据库设计人员根据需求文档，创建与数据库相关的那部分实体关系图（ERD）。如果采用面向对象方法（OOAD），这里实体相当于类（class）。5 物理设计提示：（1）主要是设计表结构。一般地，实体对应于表，实体的属性对应于表的列，实体之间的关系成为表的约束。逻辑设计中的实体大部分可以转换成物理设计中的表，但是它们并不一定是一一对应的。（2）对表结构进行规范化处理（第三范式）。5.1 表汇总

5、定单位时间如果量大可以按每天,如果不大可以按每月。表字段的区别度：主要是考虑到将来在此字段上建立索引类型选择时作为参考,当字段值唯一时可以不考虑,当字段值不唯一时,估算一个区别度,近似即可。例如：如果一个表的NAME字段有共2000个值,其中有1999个不同值,1999/2000=0.99 越接近1区别度越高,反之区别度越低。表的并发：根据具体的业务需求预测表的并发。1表名Enter_storage数据库用户库存管理人员主键ESID 入库产品编号其他排序字段Product，date，num,storageManagerId索引字段序号字段名称数据类型（精度范围）允许为空Y/N唯一Y/N区别度默

22、发器的命名按照xx数据库设计规范中关于存储过程及触发器的命名规范命名。存储过程：根据具体得业务逻辑确定输入参数个数，类型,确定对哪几个表进行何种作。 在定义存储过程时，要使用其完成单一、相对集中的任务，不要定义已由其他提供功能的过程。例如：不要定义强制数据完整性的过程（使用完整性约束）。函数 ：函数与存储过程非常相似，它也是存储在数据库中的对象。但是可以在SQL命令中使用函数。就好像建立自己的substr函数一样触发器 ：触发器是存储在数据库中的程序，它在某一特定事件发生时执行。这些程序可以用PL/SQL和java语言编写，也可以用作c语言的调用，数据库允许用户定义这些程序，然后在相关的表，视
