拥有此数据库.. 需要识别部分和过渡依赖... 并为第三范式创建新表.. 我不知道如果我的回答是正确的，但有人可以帮助我吗？
这是表..
member_num
member_name
member_address
member_city
member_zipcode
invite_num
invite_date
accept_date
dinner_date
dinner_attended
dinner_code
dinner_descript
entree_code
entree_descript
dessrt_code
dessert_descript
member_num->member_name,member_add,member_city,member_zipcode.....
invite_num->invite_date,accept_date,dinner_date,dinner_attended...
dinner_code->dinner_descript..
entree_code->entree_descript...
dessert_code->dessert_descript..
我认为我必须创建新的属性和表格到第3范式..但我很困惑...
