Entity–attribute–value model
From Wiki @ Karl Jones dot com
Entity–attribute–value model (EAV) is a data model to describe entities where the number of attributes (properties, parameters) that can be used to describe them is potentially vast, but the number that will actually apply to a given entity is relatively modest.
In mathematics, this model is known as a sparse matrix.
Equivalent terms include:
- Object–attribute–value model
