The Geo SCADA Expert database structure comprises a set of hierarchical Classes that contain a collection of Fields, Aggregates, and Methods. The class hierarchy defines the parent-child relationships between the classes, whereby a class can be derived from another class.
Each parent class is referred to as a Base Class, and each child class is referred to as a Sub-Class. Each sub-class inherits every one of its parent classes.
Example:
The CDBPoint class inherits the CAlarmObject and CDBObject classes.
The CAlarmObject class inherits the CDBObject class.
