Answer:

Here are some examples of one-to-one relationships in the home:

One family lives in one house, and the house contains one family.

One person has one passport, and the passport can only be used by one person.

One person has one ID number, and the ID number is unique to one person.

bye In a one-to-one relationship, one record in a table is associated with one and only one record in another table. For example, in a school database, each student has only one student ID, and each student ID is assigned to only one person.
