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
