Abstract
This paper is aimed to overcome the limitation of the traditional multidimensional model in order to allow usage of numerical, textual and object-oriented information as multidimensional model measures. The ontological approach is reviewed. The formal definition of multidimensional approach is given. The idea of multidimensional and ontological approaches hybridization is discussed. The hybrid multidimensional-ontological data model requirements are proposed. The formal definitions of the metagraph data model and metagraph agent model are given. The examples of data metagraph and metagraph rule agent are discussed. The representation of object-oriented data structures in form of metagraph is given. The hybrid multidimensional-ontological data model based on metagraph approach is proposed. Predicate representation of metagraph model considered as a physical data model for metagraph approach implementation is given.
