Fuzzy and uncertain spatio-temporal database models: a constraint-based approach
Guy De Tré, Rita De Caluwe, Axel Hallez, Jörg Verstraete · Ghent University Academic Bibliography (Ghent University) · 2002
In this paper a constraint-based generalised object-oriented database model is adapted to manage spatiotemporal information. This adaptation is based on the definition of a new data type, which is suited to handle both temporal and spatial information. Generalised constraints are used to describe spatio-temporal data, to enforce integrity rules on databases, to specify the formal semantics of a database scheme and to impose selection criteria for information retrieval.
