Chapter 7: Problem 30

Suppose we are modeling marriage as a relationship between two people. When, or under what circumstances, can we model this as a one-to-one relationship?

Short Answer

Expert verified
A marriage between two people can be modeled as a one-to-one relationship if it's assumed or known that each person is only married to exactly one person and not multiple people.

Step by step solution

01

Understand one-to-one relationships

In a one-to-one relationship, every element in one set (or group) is linked to exactly one element in another set. In other words, no element in either set is associated with multiple elements in the other set. Each is unique to the other.
02

Apply understanding to marriage

In the context of marriage, if we are modeling marriage between two people, it can be considered a one-to-one relationship if each person is married to exactly one other person. This means that all individuals involved are currently participating in only one marriage.
03

Identify limitations

However, circumstances may exist where this does not hold true. For example, in societies where polygamy is accepted, one person may be married to more than one person. In these situations, a one-to-one relationship model would be inappropriate.
