The category CATEGORY_GROUP names the category groups to which a category belongs. The assignment of a category to a category group is made when the category is defined. Each category group that is specified in this category must also be defined in the parent category, CATEGORY_GROUP_LIST. The basis for this category also includes the category identifier _category_group.category_id, which is completely defined in the parent category named CATEGORY.
