LexEVS Association Logical Model

The LexGrid Model defines relationships in terms of a source and target node with an edge defined separately in the AssociationPredicate model element.  These are the construction basics for larger coded node graphs which are currently represented in a relational schema.  The performance restrictions of the relational schema have been well documented above.   A mapping of the source and target structure of LexGrid will be mapped to the structure of the higher performing graph database OrientDB.
