Modeling Our World, Second Edition, focuses on understanding the geodatabase, a robust and scalable container for geographic information. The geodatabase, a collection of geographic datasets, works in concert with ArcGIS software to provide a rich framework for modeling attributes, spatial and temporal relationships, and transactions. This book promotes best practices for data modeling and analysis by addressing critical topics such as spatial integrity, attribute integrity, work flow, and scaling. Modeling Our World clarifies geographic data modeling concepts and is your complete survey of the geodatabase information model.
