Data model (ArcGIS)
In ArcGIS, a data model a set of database design specifications for objects in a GIS application. A data model describes the thematic layers used in the applications (for example, hamburger stands, roads, and counties); their spatial representation (for example, point, line, or polygon); their attributes; their integrity rules and relationships (for example, counties must nest within states); their cartographic portrayal; and their Metadata requirements.[1]
With the ArcGIS platform, the Esri vision is to build many industry-specific data models. The basic goals are to simplify the process of implementing projects, and to promote and support standards that exist in our user communities. Academic and industry leaders collaborate with Esri to create and design data model templates that can be used with one GIS platform. The result is this set of data model structures that can be implemented for each of the industries and scientific disciplines that Esri serves.
