JPA vs. Hibernate

Advantages

This section will look at the advantages of using both JPA vs. Hibernate.

JPA

• JPA supports POJO-POJI model programming.
• JPA is Light –Weight technology to develop DB independent persistence logic. 
• O/R mapping and database access processing make programming tasks simple.
• The code required to create definition files is reduced using annotations.

Hibernate

• While storing the records in the database, Hibernate can construct primary keys automatically.
• Hibernate features its database-independent query language called the hibernate query language.
• Hibernate supports mechanisms for caching. Adopting this caching strategy will improve an application's performance naturally as fewer round trips between the application and the database are required.
• In addition to XML, Hibernate also supports annotations.

Disadvantages

This section will look at the disadvantages of using both JPA vs. Hibernate.

JPA

• JPA is a specification, not a product, so you need a provider to offer an implementation to take advantage of these standards-based APIs.
• Before it is stable, the JPA specification may need to go through significant changes.

Hibernate

• Some queries supported by JDBC by Hibernate are not supported. To insert each object, a developer must create a different query.
• The number of tables in a small project will be lower. Thus it would be unnecessary to introduce the complete Hibernate framework.
• Understanding the code is challenging because we must define the mapping and input data into the XML file when there are joins and mappings between the tables.

Frequently Asked Questions

What exactly is JPQL?

The Java Persistence Query Language (JPQL) is a term that refers to the JPA specification. It is applied when creating the queries.

What is ORM?

The term "ORM" stands for "Object/Relational Mapping." The mapping of objects to the data kept in the database is a programming technique. It makes data access, data manipulation, and data generation easier.

Is JPA an ORM?

JPA is regarded as a typical ORM strategy. It is a Java specification used to manage and persist data between relational and Java object databases.

What is hibernate?

Hibernate is an open-source, compact ORM utility for storing, modifying, and retrieving data from databases.
