    摘要： A method for mapping a data source of an unknown configuration to that of a known configuration, comprising the steps of submitting a request for metadata to the data source of the unknown configuration; generating a relational schema from the known configuration based on the metadata received from the data source of the unknown configuration; and returning the metadata of the generated relational schema which maps the data source of the unknown configuration to the known configuration. In a preferred embodiment data source of the unknown configuration is a multidimensional database and the known configuration is a star or snowflake relational schema.

    摘要： An improved bias field assembly for reducing power losses in a magnetic domain memory device. A preferred embodiment employs rectangular permanent magnets positioned above and below a drive coil/substrates assembly. Ferrite shields of the same general size as the permanent magnets are interposed between the magnets and the drive coil/substrates assembly. These shields provide a highly resistive, relatively impermeable path for induced eddy currents and flux to reduce the effective resistance of the drive coil during high frequency operation and to minimize hysteresis losses.
