Abstract
PURPOSE:To reduce the CPU time, by picking up and storing the data from the original data base as one view corresponding data and picking up the data from the view corresponding data according to the access request. CONSTITUTION:According to a program, the view 4 described with the logical operation symbol is given between this program and the data base, and according to the description of this view, from the data file 3 on the data base, the data 5 corresponding to the view is picked up to be one file, for example. Further, based on the access from the program, the view corresponding data 5 is accessed and processed. Further, if renewal is produced to the data file being the original of the view corresponding data pickup, the view corresponding data 5 is renewed through the renewal processing section 6 based on the logic described in the view 4.
