A dynamic database management system includes a data dictionary, a data importer and a query front-end. The data importer automatically imports data from an input file into a database, while adding new tables for new attributes as necessary, and updating parameters and folders tables in the data dictionary accordingly, so that end-users may access the imported data by database queries through the query frontend.
