| Abstract: | Cartesian product (CP) files have been shown to be very effective for partial match retrieval. Further the Disk Modulo (DM) allocation method has been shown to be a simple and effective method for allocating CP files onto multiple independently accessible disks to further facilitate partial match retrieval. In this paper, a useful criterion for the DM method to be the best allocation method for a given CP file is presented. The presented criterion is much more general than that suggested previously which makes the DM allocation method much more applicable for real applications. |
