Entity-Relationship (ER) and Object-Oriented (OO) formalisms are often used to model
environmental information of databases or computer programs. The majority of the …

Integrity constraints can control topological relations of objects in spatial databases. These
constraints can be modelled using formal languages such as the spatial extension of the …

Enterprise information systems in agriculture and environment are becoming more complex
and difficult to design and implement. This paper aims to show our vision on using model …

Data warehouses have demonstrated their applicability in numerous application fields such
as agriculture, the environment and health. This paper proposes a general framework for …

This paper intends to classify, review, and compare the existing languages for the
specification of spatial integrity constraints at the conceptual level. We classify these …

Imposing integrity constraints is an efficient way to improve data quality in databases.
Effective imposition of integrity constraints requires their precise distinction and specification …

The technology driven design of more and more sophisticated GIS applications, is too
dangerous to support sound decisions, if we can not ensure the quality of the developed …

Decision support systems are interactive, computer-based information systems that provide
data and analysis tools in order to better assist managers on different levels of organization …

More and more environmental and agricultural data are now acquired with a high precision
and temporal frequency. These data are often represented in the form of rasters and are …
