Um engenho ativo para a transformação de SGBDs passivos ou semi-ativos em SGBDs ativos.

Abstract

The most Database Manager Systems - DBMS available actually present active characteristics. It means they respond automatically to some database events. However these characteristics have, in general, constraints. In the present dissertation an active layer, named Active Engine, is proposed. It is to be inserted at the top of comercial relational DBMS, aiming to extend their active characteristics with no changes in their source codes.
