An overview of the Relationship Classes toolset

Relationship classes define relationships between objects in the geodatabase. These relationships can be simple one-to-one relationships, similar to what you might create between a feature and a row in a table, or more complex one-to-many (or many-to-many) relationships between features and table rows. Some relationships specify that a given feature, row, or table is not only related to another feature but that creating, editing, or deleting one will have a specified effect on the other. These are called composite relationships, and they can be used to ensure that the links between objects in the database are maintained and up-to-date. Deleting a feature, such as a power pole, can trigger the deletion of other features, such as a transformer mounted on the pole or the maintenance records in a related table.
