What is the @Inheritance mapping in Hibernate 7 and what strategies are available?

// SINGLE_TABLE (most common):
@Entity
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name="payment_type", discriminatorType=DiscriminatorType.STRING)
public abstract class Payment {
    @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id;
    private BigDecimal amount;
}

@Entity @DiscriminatorValue("CREDIT_CARD")
public class CreditCardPayment extends Payment {
    private String cardNumber;
}

@Entity @DiscriminatorValue("BANK_TRANSFER")
public class BankTransferPayment extends Payment {
    private String iban;
}

// JOINED:
@Entity @Inheritance(strategy=InheritanceType.JOINED)
public abstract class Vehicle {
    @Id @GeneratedValue private Long id;
    private String registration;
}
@Entity @Table(name="cars") public class Car extends Vehicle { private int doors; }
