Cascade) as it clearly identifies that a vendor extension is being used.

but I don’t want to focus on bidirectional relationships just yet.

We will store certificate related information in a separate table which has following structure: Now let us define another POJO class corresponding to CERTIFICATE table so that certificate objects can be stored and retrieved into the CERTIFICATE table.

This class should also implement both the equals() and hash Code() methods so that Java can determine whether any two elements/objects are identical.

This is the key to mapping out a unidirectional relationship.

If we were to instantiate an instance of both of these objects we would be able to determine which method).

In the past we have learned about database relationships, specifically the One-to-Many as well as the Many-to-Many and One-to-One and that was all good, great and grand…

But now I want to talk about how to create those same relationships inside of Hibernate.

session.begin Transaction(); Country serbia = new Country(); Name("Serbia"); Area(34116); Continent europe = (Continent) session.load(Continent.class, 3); Country(serbia);; Transaction().commit(); This tells Hibernate that the other side of the association is responsible for managing the relationship, in other words the side where the entity represents the table that contains the foreign key value.
