A data model is a way of defining and representing real world surfaces and characteristics in GIS. There are two primary types of spatial data models: Vector and Raster. Vector data represents features as discrete points, lines, and polygons Raster data represents features as a rectangular matrix of square cells (pixels) Once you find a relevant data model, you can download a geodatabase template from the site that you can use to jump-start your design. You can build a test geodatabase, load some data into it, then test and refine the design for use within your GIS. Steps in using an ArcGIS data model as the basis for your design Vector Data Model is an object based approach to the representation of real world features.

As of 2020, this GIS website provides its users with over 250,000 datasets from over 5000 organizations. Data models and the production database. Once the product library and production database have been specified, you can associate the production database with specific data models by using the Choose Data Model Versions command. This command shows the data models in the product library that are supported by the production databases.

GIS is an abstraction of reality.
A perfect copy of reality cannot be recreated in the computer.
We create models – sets of constructs for describing & representing select aspects of the real world in a computer.
Models are composed of a mix of raster, vector, and attribute data.

Representing the “real world” in a data model has been a challenge for GIS since their inception in the 1960s. A GIS data model enables a computer to represent real geographical elements as graphical elements. Two representational models are dominant; raster (grid-based) and vector (line-based): Raster. Chapter 4 Data Models for GIS 4.1 Raster Data Models.
