: It sits between the Java application and the database, using standard Java APIs like JDBC , JTA (for transactions), and JNDI (for resource management) to handle low-level interactions. At its heart, Hibernate solves the "impedance mismatch"
In the world of Java development, is the leading Object-Relational Mapping (ORM) framework designed to bridge the gap between object-oriented programming and relational databases.
