From data mining to the preservation of database classes/concepts

The algorithm for the integration of classes/concepts which results in an ontology suitable for the preservation of database classes/concepts isa described. It has been designed by means of original research at the boundary between mathematics, computer science and concept theory. The input conceptual graph of this algorithm is determined as a solution of a data mining problem, which has been approached as inverse mapping of conceptual database design. Similarities and differences are discussed between an algorithm formalized in concept theory, which is not suitable for implementation, and algorithm for the integration of classes/concepts, which exploits the benefits of database notations.
