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.
