13. The computer system according to claim 9 further comprising: program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, to select, for all groups of corresponding data models, the group of corresponding class dependent data models or the corresponding independent data model based on the fit; and program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, to add a final data model set or model to selected data models.
