Spatio-Temporal Constraint Databases built on Object-Oriented Frameworks
نویسنده
چکیده
In my doctoral work, I focus on the deenition and formal background for an implementation of a constraint data model to be built on the top of an object-relational DBMS. My approach is designed to exploit existing spatial and temporal tools (mainly the one from Oracle8) yielding the declara-tiveness and expressiveness of constraint programming .

Fuzzy and Uncertain Spatio-Temporal Database Models: A Constraint-Based Approach
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...
متن کاملModeling spatial and temporal data in an object oriented constraint database framework
Constraints provide a flexible and uniform way to represent diverse data capturing spatio-temporal behavior, complex modeling requirements, partial and incomplete information etc, and have been used in a wide variety of application domains. Constraint databases have recently emerged to deeply integrate data captured by constraints in databases. This thesis is aimed at defining a constraint data...
