in reply to Associative Database
| The Associative Model of Data is an alternative
| data model for database systems.
| Other data models, such as the relational model
| and the object data model are record-based.
| Record-based models involve encompassing
| attributes about a thing, such as a car in a
| record structure (where attributes might be
| registration, colour, make, model, etc).
| In the associative model, everything which has
| “discrete independent existence” is modeled as an
| entity, and relationships between them are modeled
| as associations.
