Abstract

PURPOSE:To reduce not only the input and output time but the time for the constitution process of the file, by performing the constitution process of the formation file in such way that the input and the output may always be processes in order to the mobile memory device through which the file is produced. CONSTITUTION:The records of the data region are supplied successively, and only the key is delivered successively to the different work file to produce the file of only the key. Then the directory region is produced successively from its head and with every bucket. The head key of the work file is supplied and then converted into the bucket address through the hash method. And in the case of the address of the bucket 1, the key and its record address are produced on the buffer in the form of the record of the directory region. In such way, the processes are carried out successively. Then the bucket 1 produced on the buffer is delivered to the directory region. The above process is given successively for the buckets 2 and 3 to produce the directory region.
