Code:
@Entity
@Table(name = "TBL_DATATREE")
@SequenceGenerator(name = "SEQUENCE", sequenceName = "SQ_TBL", allocationSize = 1)
public class ProjectDataTree extends CHibernate implements Serializable
{

   /** automatisch generiert */
   private static final long serialVersionUID = -271046672593565385L;

   @Id
   @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEQUENCE")
   @Column(name = "NDATAID", precision = 18, scale = 0)
   long l_DataId;

   @Column(name = "NPARENTDATAID", precision = 18, scale = 0, insertable = false, updatable = false)
   private Long l_ParentDataId;

   @Column(name = "NTYPE", precision = 18, scale = 0, updatable = false, insertable = false)
   private long l_Type;

   @Column(name = "NREFID", precision = 18, scale = 0, updatable = false, insertable = false)
   private long l_RefId;

   // Any Mapping
   @Any(metaColumn = @Column(name = "NTYPE"),  fetch = FetchType.EAGER)
   @AnyMetaDef(idType = "long", metaType = "string",  metaValues = {
         @MetaValue(targetEntity = Car.class, value = "1"),
         @MetaValue(targetEntity = Brand.class, value = "2"),
         @MetaValue(targetEntity = Model.class, value = "3") })
   @JoinColumn(name = "NREFID")
   private Object obj_Object;

   // Mapping Vater-Kind Beziehung auf diese Tabelle
   @ManyToOne(fetch = FetchType.EAGER, optional = true)
   @JoinColumn(name = "NPARENTDATAID", nullable = true)
   private ProjectDataTree obj_ParentNode = null;

   @OneToMany(fetch = FetchType.EAGER, mappedBy = "obj_ParentNode", orphanRemoval = true)
   @OrderBy("l_DataId desc")
   private Set<ProjectDataTree> hs_ChildrenNodes = new HashSet<ProjectDataTree>(0);
       /.. Getter u. Setter
}


wie werden die Daten am besten in der Datenbank gespeichert. Gibt es die Möglicchkeit Parent and Child geleichzeitig zu speichern?

Danke
Salamunti
