The document discusses the entity-attribute-value (EAV) data model used in Magento, where attributes are stored in a separate table rather than columns. EAV provides flexibility but can result in inefficient queries; solutions include using a pivot table or Amazon SimpleDB which avoids complex queries and requires no database administration.
