Abstract
PURPOSE:To realize the effective retrieval of a record with no recompilation of a file at all, by always setting the effective records at the head of the file and accordingly increasing the efficiency of storage. CONSTITUTION:When a file access reguester 2 gives a request for reference, replacement, addition, deletion, etc. of a record,a file access controlling part gives access to the desired record of a compiling file 8 with key provided in an auxiliary storage device 9 while referring and replaceing a maximum record number indicating part 4, an effective record number indicating part 5 and a current record indicating part 6, respectively. As the effective records are stored at and after the head of the file 8, the value of the part 5 indicates the final effective record number by giving 1,2,3- of the record numbers to and after the head of the file.
