What are Ontologies?

Ontologies list the terms and their relationships that allow communication among partners in enterprises (in machine-readable form)

Relationships determine meaning - parent, school, company

Databases use ontologies during design in their E-R diagrams (Implicitly) and represent the leaf nodes in their schemas

Knowledge-bases use ontologies (often implicitely) add class definition (to hold instances), constraints, and operations among the terms
