What are some examples of database relationships?

There are three main types of database relationships: one-to-one, one-to-many, and many-to-many. Would you like to know more about each?

Yes, please explain one-to-many relationships.

In a one-to-many relationship, a single record in one table can be associated with multiple records in another table. For example, a customer can have multiple orders.

Can you give me an example of a many-to-many relationship?

MagicBuddy

Sure! A many-to-many relationship occurs when multiple records in one table are related to multiple records in another table. For instance, students and courses: a student can enroll in many courses, and each course can have many students.

What about one-to-one relationships?

In a one-to-one relationship, a record in one table is linked to only one record in another table. An example is a person and their passport; each person can have only one passport.
