Rails has two ways to model many-to-many relationships: has_and_belongs_to_many and has_many :through, this gem introduces a third one: has_many_with_set. has_many_with_set is equivalent to has_and_belongs_to_many in functionality. It works only when you do not want information about a relationship but the relationship itself, behind the curtains though, they do not work anything alike, has_many_with_set is far more efficient in terms of data size as it reduces the redundancy that occurs in a normal many-to-many relationships when the cardinality is low, that is, the same combination occurs many times. For example, in a blog application, when many posts share the same tags.
