A generic object type; that is, a class from which other, more specific classes are derived genetically by inheritance. Also called a "superclass" by people who respect their ancestors.

A class from which another more specialized class is derived, which defines a portion of the interface and/or implementation of the derived class. See also derived class

and a specific derived class

Perl supplies no such restriction, though you may certainly program Perl that way if you like.

A base class is a table which is extended but does not extend any other tables.
