In the fast decades, the execution of various scientific experiments aiming at a mare comprehensive understanding of our environment, has shown a tremendous increase in data production. Database models provide a more or less adequate mechanism for mapping well-favoured applications into a computer-bound reality. Since scientific knowledge can be modelled a-priori only to same extent, the question which arises here is how able is a database schema to evolve. On the other side, knowledge can be provided by the underlying scientific data on which data mining algorithms are applied. The main question which arises here is how to provide a suitable environment in order to accommodate the results coming out from data analysis tasks and how these casks can be supported bq a database model.
