Um protótipo completo de um sistema de informação orientado a objetos em Smalltalk

Abstract

This work presents a complete information system written in Smalltalk using the object-oriented paradigm. The system is designed as a tool for the operational control of a typical library. The essential aspects of this programming paradigm are examined, mainly data and programs encapsulation, re-usability of pre-defined objects, class hierarchy, polymorphism and automatic modularization.
