Active Record Pattern

• In the ActiveRecord you have one domain object that both knows all the business logic and how to save/update itself in the database, user.getLinkToProfile() and User::find(1), User::save(user)

Therefore, typical implementations of the Active Record pattern consist of instance properties representing a record’s fields in the database, instance methods that act on that specific record and static methods acting on all records, i.e. the database table or view.
