I was wondering if somone could clear something up for me.
I understand that if there is a database with for example:
table_Cars(reg_num)
table_Customers(cust_num, cust_name)
there is a many to many relationship and so the inclution of
table_Order(hire_date, reg_num, cust_num)
would eliminate this.
I understand this but where I get confused is what would be done if a customer could hire out more than one car on the same order.
a Car can have MANY orders and and order can have MANY cars.
back to square one.
any guidence on this subject would be appriciated!
thanks
