ConTOM: um sistema de consultas gráficas a um branco de dados temporal orientado a objetos.

Abstract

This paper presents the Graphical Database Query System - ConTOM (TOM Consultations), considering as relevant aspects: the visual specification of the conceptual scheme from a modular perspective, and the process of specifying a query consisting of graphical operators that are performed by direct manipulation of schema objects conceptual. ConTOM fully exploits visual representation, reducing to a minimum required textual data. The graphic operators are divided into basic and temporal operators. The latter manipulate temporal comics, integrating the visual representation with the specification of temporal queries. THE query result and a subschema with the same schema structure can be reused. The paper also presents: a formalization of the conceptual scheme and all graphical operators, a comparative study between ConTOM and other graphical interfaces, and the tool's interface design Count
