I'm looking for some guidence on managing a parent child relationship
when the parent can have many children -
so a simple 1-many relationship is set up
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable = "false")
public class parent {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String key;
@Persistent(mappedBy = "catagory")
private ArrayList<DataPoint> points;
