Nonspatial tables

You've learned that the geodatabase is a relational database. A relational database is composed entirely of tables. Most of these tables are hidden from you when you work with a geodatabase in ArcCatalog or ArcMap. Your interaction with the tables is managed by the software. There are only two types of tables that you interact with directly: feature class tables and nonspatial tables.

Both types of tables are created and managed in ArcCatalog and edited in ArcMap. Both display in the traditional row-and-column format. The difference is that feature class tables have one or more columns that store feature geometry.

Nonspatial tables contain only attribute data (no feature geometry) and display in ArcCatalog with the table icon Table. They exist in a geodatabase as standalone tables, and they can be associated with other tables or feature classes. When a nonspatial table is associated with a feature class, you can query, select, and symbolize features based on the data stored in the nonspatial table. You'll learn more about associating tables in lab 9
