MODGRID – An environment in the WEB for the development and execution of spatial models in a Computational Grid

Collaboration among researchers is not found only in data exchange, but also in the interaction between the scientific models and their implementations, as well as in the aggregation of experiment programs and results. Besides, the researchers need an environment which renders possible the support of geographically distributed collaboration groups, to intensify the exchange of scientific resources. This work presents the MODGRID system, part of a technological infrastructure developed within the DESENSUS Project, where users can remotely access, share programs and data, as well as the scientific workflow and experiments definitions. Contribution of this work lies in studying how the proposed architecture can incorporate the database systems of current Computational Grid technologies.
