A method of managing cells formed from a tuple of members in a multidimensional database include treating at least one dimension in the database as a plurality of hierarchically structured members divided into at least two levels, thereby defining a validation curve as the location of an intersection of the levels. What level the cells in the database are located is evaluated. Cells contained in a lower level are managed by automatically indicating them as one of valid and invalid at data load time, and cells contained in an upper level are managed by indicating them as one of valid and invalid according to a method involving at least one of less reading from and writing to the database at data load time than if all the cells in the upper level were indicated as one of valid and invalid at data load time. A computerized database management system uses a communication interface to practice the method.
