JPA Annotation Attribute in jakarta.persistence. ManyToMany String mappedBy default "" The field that owns the relationship. Required unless the relationship is unidirectional. Since: JPA 1.0

JPA Annotation Attribute in jakarta.persistence. ManyToMany FetchType fetch default FetchType.LAZY (Optional) Whether the association should be lazily loaded or must be eagerly fetched. The EAGER strategy is a requirement on the persistence provider runtime that the associated entity

JPA Annotation Attribute in jakarta.persistence. ManyToMany CascadeType [] cascade default {} (Optional) The operations that must be cascaded to the target of the association. When the target collection is a java.util.Map , the cascade element applies to the map value. Defaults to no operations being cascaded. Since: JPA 1.0

hi,   what is the purpose of annotating a field with a RDB relationship shuch as OneToMany. ManyToMany etc? sprintf Reuben Alfred Using these annotations is optional in ObjectDB but required by standard JPA. You still need these annotations in ObjectDB to specify cascading / fetch policy and other settings. support Support
