Timbr semantic graph relationships enable users to define inheritance in SQL to simplify data consumption. An inheritance is a relationship between two or more hierarchies of concepts in which the attributes and relationships of the parent concepts are inherited to the lower hierarchy. This is very similar to inheritance in OODBs and PLs such as C++.
Example of inheritance relationship:
Alcoholic and Non-Alcoholic Drinks inherit from Beverage, since (necessarily) anything that is a member of the Drinks class is a member of the Beverage class. The inheritance relationship is used to create a hierarchy of classes, typically with a maximally general class named thing at the top, and very specific classes like Orange Juice at the bottom. The critically important consequence of the inheritance relation is the inheritance of properties from the parent (inheriting) class to the child (inherited) class. Thus, anything that is necessarily true of a parent class such as Beverage is also necessarily true of all of its inherited child classes, one of them being Orange Juice.
