摘要： A memory device with a redundant disk array. In order to quicken the processing of data writing into the redundant disk array, a first cache memory for accessing the redundant disk array, a second cache memory for storing old data of the first cache memory when the data of the first cache memory are renewed, and a third cache memory for storing old CK data read out of the redundant disk array when the data of the first cache memory are renewed are provided. New CK data are produced from new data for the renewal, old data stored in the second cache memory and old CK data stored in the third cache memory, and the new data for the renewal and the new CK data are stored into data storage means and CK data storage means of the redundant disk array. Since, the data read out of the cache memories are processed without reading the old data and the old CK data out of the redundant disk array, the number of accesses into the disk array at a data writing time can be reduced, and data writing can be performed at a quick speed.

摘要： A data allocator which allocates data and redundant data for recovering the data. The data allocator has k storage groups, each of which includes m array files. Each array file includes multiple memory areas for storing the data and the redundant data on a block basis. A redundant group is formed which consists of k memory areas, each of which is selected from the same row of each one of k storage groups, and one of the k memory areas stores the redundant data and the remaining (k-1) memory areas store the data. The redundant data are uniformly allocated to m.sup.k sets of memory areas (D.sub.ij1, D.sub.2j2, . . . , D.sub.kjk) of the same rows of the storage groups, where j.sub.i (j.sub.i =1-m) is the number of the array file in each of the storage groups, and D.sub.kjk is the memory area belonging to k-th storage group and j.sub.k -th array file of the k-th storage group. This makes it possible to prevent an increase in the number of accesses to particular array files and the reduction in the data read rate even if one of the array files fails.

摘要： A data transfer for high-speed data transfer between two memories comprises three buffers for temporarily storing data being transferred, a source side controller for switching the buffers and for transferring the data in terms of blocks in such a manner that the leading buffer coincides with the address boundary of the source memory, and a destination side controller for switching the buffers and for controlling the transfer of data in terms of blocks. By switching over the buffers one after another, the data transfer from the source memory to the data transfer apparatus and the data transfer from the data transfer apparatus to the destination memory can take place simultaneously.

摘要： In a data processing system for management of a relational data base stored among a plurality of disc storage units, a method and apparatus for horizontally partitioning a physical page on the basis of tuples includes a master processor, a master disc storage unit coupled to the master processor, a plurality of slave processors controlled by the master processor, and a plurality of slave disc storage units, one coupled to each of the slave processors. The master disc storage unit stores, in the form of a B-tree structure, a clustered index for either an attribute or a relation to be processed in the relational data base. The plurality of slave disc storage units store divisionally a relation in the data base which is partitioned on the basis of a page for a clustered index thereof in such a manner that the plurality of slave processors may execute, in parallel, a plurality of processings on a cluster of tuples, as defined in their range in connection with a given key value of the clustered index.
