dc.description.abstract | Este documento demonstra que o modelo matemático obtido pela adição de uma função a uma relação, e que a possa ordenar, demonstrando que a propriedade de fecho das operações entre relações se mantém, pode constituir uma extensão do modelo relacional. | pt_PT |
dc.description.abstract | This document approaches the possibility of adding a mathematical function to a relation that could sort that relation, demonstrating that the closure property of relations are still kept, so that this mathematical model can be used as extension of the base relational model. | pt_PT |
