 There are two types of attributes you can use to extend Magento functionality:
 
-* Custom and Entity-Attribute-Value (EAV) attributes—Custom attributes are those added on behalf of a merchant. For example, a merchant might need to add attributes to describe products, such as shape or volume. A merchant can add these attributes on the {% glossarytooltip 29ddb393-ca22-4df9-a8d4-0024d75739b1 %}admin{% endglossarytooltip %} panel. See the [merchant documentation](http://docs.magento.com/m2/ce/user_guide/stores/attributes.html) for information about managing custom attributes.

 	Custom attributes are a subset of EAV attributes. Objects that use EAV attributes typically store values in several MySQL tables. The `Customer` and `Catalog` modules are the primary models that use EAV attributes. Other modules, such as `ConfigurableProduct`, `GiftMessage`, and `Tax`, use the EAV functionality for `Catalog`.
