Data mapper patterns are design patterns that separate the in-memory objects from the database. They help in mapping data between objects and database tables.

What are some advantages of using data mapper patterns?
Some advantages include better separation of concerns, easier testing, and the ability to change the database without affecting the domain model.
Are there any popular frameworks that implement data mapper patterns?
Yes, some popular frameworks include Doctrine for PHP and Hibernate for Java, both of which utilize data mapper patterns.
