# QlikView Object ownership hierarchy

The seven most basic classes in QlikView form a classical object hierarchy, where objects of a class are parents to children objects of another class. A child object cannot exist without its parent object, but does not inherit any of the parent’s member methods or properties.

A schematic representation of the hierarchy could look as follows:

Tip noteLEGEND: downward arrows point at children class and upward arrows point at parent class.
