The BaseTable class is the class from which both PrimaryKeyTable and VirtualTable are derived. It represents a set of records in a database table, view or a joined table as a result of a query. This class provides the basic methods common to both the PrimaryKeyTable and VirtualTable classes. This class cannot be instantiated directly; instead, only derived classes can be instantiated. All classes that reference the database derive classes from this class.
The methods in this class can be overridden to provide additional functionality. The recommended place to override these methods is in the customizable class of the specific table.
