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.

Description

In mathematics, this model is known as a sparse matrix.

Equivalent terms include:

  • Object–attribute–value model
  • Vertical database model
  • Open schema
