Overview of this book

This is a solution-based book, showcasing the real power of ArcGIS Geodatabase by following a real-world, example-based approach. This book is aimed at geospatial developers who want to work with ArcGIS geodatabases as well as manage them. Having knowledge of building a geodatabase from scratch isn't a must; Learning ArcGIS Geodatabases is ideal for those who want to use ArcGIS geodatabase for the first time, or for those who want to migrate from their existing legacy database to a geodatabase.

Working with feature classes

Let's start with the feature classes. We have already learned how to create a new feature class. In this section, we will learn how to add and delete attributes and work with the concept of subtypes and domains.

Note

A subtype is a subset of the features in a given feature class sharing the same attributes.

A domain is a range of the possible values for a given attribute. It is usually used to avoid erroneous entries.

Adding new attributes

Your client for the Bestaurants project reviewed your initial geodatabase and suggested some changes. They noticed that you have a name field for each feature class, but they need to have the DESCRIPTION and REVIEW attributes, which can help the customers by giving them more descriptive information about a particular restaurant. To add these attributes, perform the following steps (make sure all instances of ArcMap and ArcCatalog are closed):

  1. Open a fresh session of ArcCatalog and browse to the Bestaurants geodatabase. Start...
