Erc Sets and Antimatroids

Grammars in Optimality Theory can be characterized by sets of Ercs (Elementary Ranking Conditions). Antimatroids are structures that arose initially in the study of lattices. In this paper we prove that antimatroids and consistent Erc sets have the same formal structures. We do so by defining two functions MChain and RCerc, MChain being a function from consistent sets of Ercs to antimatroids an...

ERC+: an object+relationship paradigm for database applications

The concepts of object oriented data models aim towards modeling of application objects close to the user's view. Yet developers of applications relying on object oriented database management systems are facing problems resulting from the limitations of object oriented data models to describe adequately the full range of possible associations between objects and between processes. This paper fo...
