One easy way to achieve this is to separate pure business
logic from the persistence mechanism. Implement the
business logic in your CMP class, which can be deployed
alone if CMP is chosen. Then implement the persistence code
into the BMP class, which inherits from the CMP class. This
preserves all the business logic of the CMP superclass and
adds database access code in the BMP subclass,
This model sounds easy to implement but still leaves the
following flexibility inhibitors:
It is impossible to extend the implementation classes.
Doing so means the subclasses must extend both the CMP and
the BMP superclass directly. In addition, the BMP subclass
will have to extend its direct CMP implementation. This
causes multiple class inheritance. Such multiple
inheritance is not allowed in Java programming
