Title: Programmed digital data processing system
IPC: G06F7/24
Filed: 1972-11-29
Abstract: 1405277 Digital computers; data sorting and retrieval INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1972 [16 Dec 1971] 55084/72 Headings G4M and G4A A digital data processing system is programmed to sequentially retrieve records scattered at dispersed addresses in a storage device. It is based upon the principle that the recovery of data records is analogous to their distribution. Each record has a tag including its key value, the device area where it is located and its address in that area. A directory contains the tags in sequential order of key value, thus a tag is a directory record. A portion of the main store is utilized for a chosen quantity of directory records, distribution for the directory records is simulated, and the result is written as an output string containing the address portions of the tags in the order they were written out and grouped according to area and data items as to which areas are to be visited at a particular juncture and the amount of records which can be recovered from an area when it is visited. Once the string has been generated, retrieval can be performed using the items on the output string in the reverse order to which they were written out. Distribution simulation.-This comprises the steps of: (a) Filling the main store with the chosen quantity. (b) Selecting an area. (c) Writing out the address of the earliest directory record in main store which is to go to the selected area in the distribution simulation as the next item in the output string. (d) Replacing the written out record with the next directory record (unless the directory is empty) and iteratively repeating steps (c) and (d) until all the records for the selected area have been written out. (e) Writing out on the string items representing the amount of records which can be written out at a visit to the selected area, the area number, and the number of records. (f) Selecting another area. (g) Iteratively repeating steps (c)-(f) until all the directory items have been written out on the output string.
