Abstract in Portuguese
É apresentada a explicitação do modelo matemático implícito no desenvolvimento do Sistema PSL/PSA. do Projeto 18005, em sua versão plena. E evidenciado que este modelo é um hipergrafo dirigido, categorizado, com rótulos, e além disso. que se pode representa-lo através de dígrafos categorizados com rótulos. É discutido um trabalho de Durchholz sobre representação de relações por matrizes e por Funções, no contexto de modelos matemáticos de Sistemas de Informação, que adaptam-se aos quatro enfoques abordados por esse autor.

Abstract in English
It is presented here, the explicitation of the mathematical model implicit in the developement of the PSL/PSA System of ISDDS Project, in its complete version. It is made evident that this model is a directed.categorizai hipergraph with labels. and moreover, that one can represent it by categorized digraphs with labels. It is also discussed a paper by Durchholz about reprg sentation of relations by matrixes and by functions in the context of mathema tical models of Information Systems that suit the four approaches mentioned by this author.
