Detailed explanation-1: -Entity inheritance means that we can use polymorphic queries for retrieving all the subclass entities when querying for a superclass. Since Hibernate is a JPA implementation, it contains all of the above as well as a few Hibernate-specific features related to inheritance.

Detailed explanation-2: -Hibernate supports the three basic inheritance mapping strategies: table per class hierarchy. table per subclass. table per concrete class.

Detailed explanation-3: -Inheritance-It is used to define the type of inheritance used in hibernate and it is defined in the parent class. If the Inheritance annotation is not specified or if no inheritance type is specified for an entity class hierarchy, the SINGLE TABLE mapping strategy is used.

Detailed explanation-4: -Single Table. The single table strategy maps all entities of the inheritance structure to the same database table. This approach makes polymorphic queries very efficient and provides the best performance.
