JPA and Hibernate provide different methods to persist new and to update existing entities. You can choose between JPA’s persist and merge and Hibernate’s save and update methods.
It seems like there are 2 pairs of 2 methods that do the same. You can use the methods persist and save to store a new entity and the methods merge and update to store the changes of a detached entity in the database.
