Difference between Hibernate and JPA Java applications traditionally used technologies like JDBC (Java Database Connectivity) to access relational databases in order to store data persistently. Hibernate on the other hand is a java based framework which also facilitates the interaction of application objects with a database but in a completely different approach.. Below are listed some differences between the two. Hibernate is just one persistence provider which is a fine choice. Hibernate is flexible and powerful ORM solution to map Java classes to database tables. There is no code that will allow you to access the database. If you are comfortable with straight JDBC then I would go ahead and start delving into the world of ORM and learn that next, but definitely in that order. With JDBC, developer has to write code to map an object model's data representation to a relational data model and its corresponding database schema. Almost all of enterprise applications are required to access relational databases regularly. It generally rides on top of JDBC. JPA is a lightweight alternative to Enterprise JavaBeans (EJB), and was developed to be easier and use fewer resources. JPA vs. Hibernate What is JPA? JDBC is acronym of Java database connectivity. JPA is an ORM that attempts to minimize the impedance mismatch between a procedural language and an SQL data store. It is an open source Java api. You can also use JPA instead of writing SQL code using JDBC. Hibernate . unlike jdbc, hibernate connects with the database itself and uses hql (hibernate query language) to execute the queries, then maps the results to java objects. Hibernate itself takes care … Relational persistence for Java Hibernate is a powerful and flexible framework, as there is no need to write excess code (queries) for database connectivity. I am sure that among Spring/Hibernate developers, there are a lot confuses about the concepts of JPA transaction, Hibernate sessions and JDBC connections and even DB transactions, sometimes these kind of confuses can impact the application design and issues investigation, so let's make some clarification about these concepts. JPA vs Hibernate . JDBC is an API used to map data. On top of that there is JPA which is a specification. Hibernate is also used for connect your application to database and to do database related transactions but with different approach. Hibernate: JDBC: Usage Hibernate is an ORM tool used to map persistent objects. It is considered as a standard approach for Object Relational Mapping. JDBC is an acronym for J ava D ata B ase C onnectivity and is a technology for interaction of java application and its objects with a database. But a problem faced with earlier technologies (such as JDBC) was the impedance mismatch (difference between object-oriented and relational technologies). It’s just a specification. However, JPA can’t be used by itself to access the database. I would choose this over hibernate … It is used to connect your application to the database and transactions . JDBC . The main problem was the difference between object-oriented and relational technologies. JDBC is a thin, ODBC-like, API on top of straight SQL. A JPA (Java Persistence API) is a specification of Java which is used to access, manage, and persist data between Java object and relational database.
