Modeling dynamic relationship types for subsets of entity type instances and across entity types
2016, Information SystemsCitation Excerpt :Also, this approach requires less work by the designer especially when there are dynamic and on demand relationships arise. Thus, our work enhances the non-first normal form (NF2) database model [27] where the attribute values in the relational instances can be atomic, set-valued, null or relations themselves (i.e., nested relations). ER models are widely used for conceptual database design.
