1. The result of the conceptual design process. A generalized, user-defined view of the data related to applications. 2. A formal method of describing the behavior of the real-world entities. A fully developed data model specifies entity classes, relationships between entities, integrity rules and operations on the entities. 3. ArcInfo coverages and grids use a georelational data model, a hybrid data model that combines spatial data (in coverages or grids) and attribute data (in tables). Other data models used in ArcInfo include tins, images, and grid.
