Object-Relational Mapping (ORM) is a technique for mapping objects in an object-oriented programming language to relational database tables. Hibernate is an ORM framework for Java that simplifies database interactions by automatically generating SQL queries and handling object-to-table mappings based on the defined entity classes and their associations.
For example, if you have a Java class called Customer with properties for the customer's name, address, and phone number, Hibernate can automatically generate SQL queries to insert, update, and delete customers from a database table. Hibernate can also map relationships between entities, such as one-to-one, one-to-many, and many-to-many relationships.
