| * <b>Purpose</b>: Abstract superclass for Large & Small projects in Employee Demo |
| * <p><b>Description</b>: Project is an example of an abstract superclass. It demonstrates how class inheritance can be mapped to database tables. |
| * It's subclasses are concrete and may or may not add columns through additional tables. The PROJ_TYPE field in the |
| * database table indicates which subclass to instantiate. Projects are involved in a M:M relationship with employees. |
| * The Employee classs maintains the definition of the relation table. |
