looking at eav_setup file and trying to understand the difference between the eav/attribute and eav/entity_attribute table.



If I have to guess,
eav/attribute is the entity that represents the concept of attribute



eav/entity_attribute is also an attribute which additionally carries the concept of



  • attribute (the actual attribute)

  • entity type that I can describe (entity_type_id)

  • attribute set that I belong (attribute_set_id)

  • attribute group that I belong (attribute_group_id)

I'm not sure about the entity_type_id



When I create attribute in magento admin, I create the raw eav/attribute.

When I assign it to attribute set in the admin, I create the eav/entity_attribute. (but where does entity_type_id come from?)



Above statements are purely guesswork, please correct me if I'm wrong.
