Means that the set of rules and guidelines for creating the APIs. If says another context, It is set of standards which provides the wrapper for creating those APIs , can be use for accessing entity object from database.

JPA is provided by oracle. When we are going to do database access , we definitely needs its implementation. You must have interface implementation to use interface. But you can use class through interface, i. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?

Viewed k times. Anthony Anthony Battle Hibernate vs JPA is pointless. Amine , If we have been already know that that above question is incorrect. We don't need ask anymore. I also interest on this topic. I have a confusion with JpaTemplate used in spring "org. JpaTemplate" it has his own functions like persist ,find ,merge etc. If you still need an answer, I suggest you ask your own question separately to attract more feedback.

Active Oldest Votes. Kevin Bowersox Kevin Bowersox I just wanted to add that replacing one ORM with a different one is a very rare occasion, so you would probably never get this benefit out of using JPA.

What you gain with JPA is a protocol, standards, naming and other conventions that you can use to communicate with others. JavaGeek that is true as long as one's code is using only interface mentioned in JPA. If one uses features specific to hibernate then they have to use the org. Show 1 more comment. JPA is the dance, Hibernate is the dancer. JPA is the Art, Hibernate is the artist. I like this sense of humor : JPA is a director, Hibernate is an actor.

This answer does not explain anything, just a vague saying. This metaphor does not add understanding. If you already know the difference, you'll find it amuzing. If you don't know the difference, you will still not know it. Show 12 more comments. Jordi Castilla Ken Block Ken Block 3, 1 1 gold badge 20 20 silver badges 22 22 bronze badges.

Good history part. Thanks for thoses enlightening precisions. You said JPA was done because applications where tighly coupled with Hibernate, it was a need for abstraction, ok. But isn't it an infinite problem? Isn't the application now tighly coupled to JPA instead? What is the real benefit in here? I already see Hibernate as an abstraction Layer Aphax Sure, and when you code.

Now we need to incorporate a framework to be discussed. Yes, you guessed it right, hibernate. It is a java framework, open-source, lightweight, and ORM Object Relational Mapping tool for the java language which simplifies the buildout of Java application to interact with the database. It is used to save the Java objects in the relational database system. It was initially released on 23 May It supports a cross-platform JVM and is written in Java.

The main feature of Hibernate is to map the Java classes to database tables. It helps in mapping Java data types to SQL data types. It is the contributor of JPA. Now you must be wondering out why there is need for JPA, right. So let us discuss the need of JPA before proceeding to differences between them to get cutthroat differences between them. So as illustrated, JPA is a specification. It gives common functionality and prototype to ORM tools. All ORM tools such as Hibernate follow the common standards, by executing the same specification.

Subsequently, if we need to switch our application from one ORM tool to another then we can easily do it. By now we have discussed both the concepts and their suitable needs.

Now ley us jump to the differences between JPA and hibernate and wrap up the article. As we know that JPA is only a specification which means that there is no implementation.
