Static method to get an instance of an SDO_DAS_DataFactory.
This instance is initially only configured with the basic SDO types.
A Data Access Service is responsible for populating
the data factory model and then allowing PHP applications
to create SDOs based on the model through the SDO_DataFactory interface.
PHP applications should always obtain a data factory from a
configured Data Access Service, not through this interface.
Return Values
Returns an SDO_DAS_DataFactory.
