An Extension of the Relational Data Model to Incorporate Ordered
... There is strong evidence in recent research that ordering is inherent to the underlying structure of data in many database applications [Buneman et al. 1991; Maier and Vance 1993; Read 1995; Libkin 1996; Raymond 1996; Wijsen 1998]. For instance, Raymond [Raymond 1996] illustrates the potential of us ...
