What is the connection between Java Domain and DAO Mapper?

edit

There is no direct connection between a Java Domain and a DAO Mapper.

A Java Domain is a set of classes that represent the application's data model, which encapsulates the application logic and the data it operates on.

On the other hand, a DAO Mapper (Data Access Object Mapper) is a design pattern that provides a layer of abstraction between the application logic and the database. It typically uses CRUD (Create, Read, Update, and Delete) operations to manage the persistence of data.

In an application, the DAO Mapper interacts with the database and returns the data in the form of Java objects, which represents the domain model. These objects can be manipulated by the application logic to perform business operations.

Therefore, the connection between Java Domain and DAO Mapper is indirect, as the DAO Mapper helps in mapping the data from the database to the Java objects that represent the domain model.
