Modeling Our World: The ESRI Guide to Geodatabase Design
"Modeling Our World: The ESRI Guide to Geodatabase Design" is a comprehensive guide that delves into the intricacies of geodatabase design using ESRI's Geographic Information System (GIS) technology. In Chapter 1, "Object Modeling and Geodatabases," the book introduces the concept of object modeling in GIS and provides an overview of geodatabases, which are the repositories for storing geographic data.
The chapter begins with a discussion on modeling objects with GIS, highlighting the progress of geographic data models over the years. It then delves into the concept of a geodatabase as a store of geographic data, and how it differs from traditional file-based data storage methods. The authors explain the features of an object-oriented data model, which allows for complex relationships and behavior to be defined for geographic objects.
The chapter also covers topics related to serving and accessing geographic data, including an overview of web-based GIS services and technologies. It provides insights on building data models, including best practices for designing and organizing geodatabases for efficient data management.
To aid in understanding the concepts discussed, the chapter provides a guide to reading UML (Unified Modeling Language) object diagrams, which are commonly used in GIS design. The chapter also discusses technology trends in geodatabase design, providing readers with insights into the latest advancements and innovations in the field.
Overall, Chapter 1 sets the foundation for understanding the fundamental concepts of object modeling and geodatabases in GIS. It provides a comprehensive overview of geodatabase design and introduces readers to the key principles and best practices for creating efficient and effective geodatabases to store and manage geographic data.
