The Physical Data Model (PDM) describes how the information represented in the Logical Data Model is actually implemented‚ how the information-exchange requirements are implemented‚ and how the data entities and their relationships are maintained. There should be a mapping from a given Logical Data Model to the Physical Data Model if both models are used. The form of the Physical Data Model can vary greatly‚ as shown in Figure 31. For some purposes‚ an additional entity-relationship style diagram

Conversion from Class to Basic Type: We know that conversion from a basic to class type can be easily done with the help of constructors. The conversion from class to basic type is indeed not that easy as it cannot be done using constructors. for this conversion we need to define an overloaded casting operator.
