Data Modelling: Help with Recursive binary relationships?
July 26th, 2011
This is literally melting my brain. here are some examples im having trouble grasping…
“A 1:N recursive relationship. An employee supervises a number of other employees, an employee is supervised by another employee”
“An N:M recursive relationship. A person is the cousin of a number of other people, a person is the cousin to a number of people.”
Can anyone please help explain these examples to me, as i don’t really understand them. Thanks
