><P
> The root of each data graph is an object of a special root type and
the application data objects come below that.
Of the various application types in the SDO model,
one has to be the the application type immediately
below the root of the data graph.
If there is only one table in the database metadata,
so the application root type can be inferred, this argument can be omitted.

each of which is an associative array containing the keys
<CODE

>
and
<CODE

>child</CODE
>.
The containment relations describe how the types in the model
are connected to form a tree.
The type specified as the application root type must be present
as one of the parent types in the containment references.
If the application only needs to work with one table at a time,
and there are no containment relations in the model,
this argument can be omitted.
