Resumo:
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
