Design of the JDM API - Java Data Mining: Strategy, Standard, and Practice - page 185

Note that the client application uses the vendor-specific Connection
instance to create a vendor-specific object factory. This enables
applications to connect to multiple vendor DMEs when developing
a data mining solution.
After the application creates an object factory using the connection,
it creates JDM objects using create methods provided in the factory
object. For example, to create a PhysicalDataSet object, users invoke the
create method in the PhysicalDataSetFactory object. Figure 8-16 depicts
PhysicalDataSetFactory -related objects. All other JDM objects follow the
same pattern to create JDM objects.
