The data access method in large-scale knowledge database system

摘要

PURPOSE:To considerably reduce processings required for conversion at the time of writing data from a main storage into a file by mutually converting data on the main storage with data on the file only by means of the conversion of an absolute address and an offset. CONSTITUTION:An external storage 6 stores multiple objects so as to constitute a knowledge data base. An input/output control part 10 is constituted to a terminal equipment 7, CPU 8 and the main storage 9 and the control part 10 functions an input/output interface connecting an electronic computer 1 with an input/output device such as the terminal equipment 7. An external storage control part 11 is connected to the device 6, CPU 8 and the main storage 9, and controls the input/output of knowledge data between the main storage 9 and the device 6. A knowledge base system (Jasmine) 12 being the core of the knowledge data base is stored in the main storage 9 in the computer 1, and CPU 8 executes various processings to the knowledge base in accordance with the program. Further, a part of knowledge data 13 is stored in the main storage 9, but conversion from data 13 into data stored in the device 6 comes into question.
