Um ambiente visual de consulta a banco de dados espaço-temporal.

Abstract

Visual Query Systems (VQS) for Spatio-Temporal Databases, which enable visual formulation of queries involving both spatial and temporal dimensions, are an important research subject. Existing results treat these dimensions separately and there are only a few integrated proposals. This dissertation presents a VQS, called Spatio-Temporal Visual Query Environment (S-TVQE) which allows for the formulation of conventional, spatial, temporal, and spatio-temporal database queries in an integrated environment. In S-TVQE the user, instead of manipulating textual queries languages will interact with visual operators to define the query conditions. The tool provides the visualization of the results in different formats such as maps, graphics, and tables.
