org.hibernate.ogm.datastore.couchdb.dialect.model.impl.CouchDBAssociation
Represents an association stored in CouchDB, backed either by an association document (external storage of associations) or an association sub-tree within an entity document (embedded storage of associations).
The owning document must be written back to CouchDB to make changes to the rows of an association persistent in the data store. @author Gunnar Morling
