Creating and editing table relationships

Objects in the real world often have particular associations with other objects. For example, factories are associated with inventory and employees. To model real-world associations between objects in a geodatabase, you can create a relationship.

A relationship can be created between two feature class tables, between a feature class table and a nonspatial table, or between two nonspatial tables. Once you have created a relationship between two tables, you can access data stored in one of the tables from the other.

Remember that, in technical terms, all objects in a geodatabase are stored in some type of object class. A relationship class is used to store table relationships. Relationship classes provide advanced functionality not available with ArcMap joins and relates. In this topic, you'll learn about this advanced functionality.
