Difference between JDBC and Hibernate?


Posted On: Jan 27, 2023


What is the Difference Between JDBC and Hibernate:

JDBC: JDBC stands for Java Database connectivity. It is an application programming interface that is free as well as open-source. The main function of JDBC is to enable applications to access various databases. It also helps the applications to create queries and update data to RDBMS (Relational Database Management Systems) using a specific query language known as SQL(Structured Query Language). The sole aim of creating JDBC was to make the application interaction as easy and as fast as possible.

The working of JDBC includes connecting the drivers to the database before executing final SQL statements. Then, ODBC drivers are used by JDBC drivers to execute the given SQL query. It does not involve any object-oriented paradigm and is entirely based on the concept of the relational database model. It operates on the data received in the form of tables and establishes references and connections between tables. It provides less flexibility than that Hibernate. Also, it is tough to migrate data to a new database when required because of the absence of the property of migration in JDBC.

Hibernate: Hibernate is an ORM(Object Relational Mapping) tool for developers made with the help of the Java ecosystem. Hibernate is very beneficial for developers as it is a free as well as and open-source tool. It acts as a vital networking platform widely used for mapping object-oriented programming concepts to an RDBMS (Relational Database Management Systems). Hibernate is an ideal tool for dealing with mismatch problems of object-relational impedance as it replaces direct and persistent database accesses with high-level object-handling functions.

It has a smooth functioning that can be used by beginner and intermediate-level coders. It basically does the work of establishing a connection to the database and then modifies every Hibernate Query Language statement into its respective database-specific statements. These statements are then mapped into Java objects which can be further identified and operated by Java applications. Unlike .jdbc, hibernate is automatic. This means it connects itself, uses its own language (HQL) for executing the queries and then maps the desired results. The results mapped at the end show the property of the Hibernate configuration XML file.
