I Need A Real World Example Of The Following Types Of Data Relationships N Many

I need a real-world example of the following types of data relationships:

  • 1:1
  • 1:M
  • M:N (many-to-many)

This example can be from work, school, a hobby, or daily life.

Also, why would making the distinction between these types of relationships be important for database designers. How does each of these types of relationships affect the complexity of storing and retrieving data? How do database architects apply the concepts of primary and foreign keys to each type of data relationship?
