Hibernate supports two main approaches for defining entity mappings:
XML mappings: Entities can be mapped using XML configuration files, where each entity class is associated with a corresponding XML file defining its mapping information. XML mappings offer flexibility and allow customization of various mapping details.
Annotation mappings: Entities can be annotated using Hibernate-specific annotations, such as @Entity, @Table, and @Column, to define the mapping information directly within the entity class. Annotation mappings provide a more compact and readable way of defining mappings and are commonly used in modern Hibernate projects.
