Resumen
In article possibilities of use of methods of the functional analysis of data during the developing and operation of information systems are discussed. Features of design of multidimensional network models of information systems are considered. The author reveals the essence of the application of a mathematical apparatus of implicative matrixes in preparation and data analysis in case of making decisions on functioning of system. The relevance of article is connected with increase of interest in a question of interpretation of semantic interrelations of structural elements at support of information systems on the basis of functional ratios.
