Abstract (English): This paper presents a system of storage and relational query of text by use of a DBMS (Database Management System). Based on the Portuguese epic poem "Os Lusíadas", we describe in detail the methodology used to identify the grammar of the ASCII text and present the development of finite automata for token recognition. We also propose a data model and present some examples of SQL (Structured Query Language) queries that illustrate some of the capabilities of the system. Finally we present some indications for future development towards a more generalized model in order to make it suitable to other textual works. [ABSTRACT FROM AUTHOR]
Abstract (Portuguese): Este trabalho apresenta um sistema de armazenamento e consulta relacional de texto fazendo uso de um SGBD (Sistema de Gestão de Base de Dados). Tendo por base o poema épico "Os Lusíadas", descreve detalhadamente a metodologia seguida para identificação da gramática do texto ASCII da obra original, bem como apresenta o desenvolvimento dos autómatos finitos de reconhecimento da linguagem da obra. Propõe ainda um modelo de dados para a estruturação de textos e apresenta alguns exemplos de consultas SQL (Structured Query Language) que ilustram algumas das suas potencialidades. Por fim indicam-se algumas pistas de desenvolvimento, nomeadamente no sentido de uma maior generalização do modelo tornando-o eventualmente aplicável a outro tipo de obras. [ABSTRACT FROM AUTHOR]
