A computer-implemented method of processing business data, the method including storing data in SPO (subject-predicate-object) format in multiple databases; using a storage layer to connect to the multiple databases and maintaining a record of which data is stored in which database, the data comprising rules and axioms, the axioms representing user data; the rules and the axioms stored in the SPO format; at least one ontology representing a union of at least some rules and axioms that represent a particular data interpretation; a storage layer that permits working with data stored in different databases simultaneously and permits a user to use data from several storages simultaneously; transforming the user data based on context provided by a business application that works with specific objects and ontologies, the context being defined by a particular ontology; performing operations on the data based on triggers specified by the rules; generating new data in the same context; processing requests from a business layer to transform the data; and presenting the data to the user based on the context.
