Filed: 1985-08-01
Abstract: PURPOSE:To omit the useless renewal processing of a control table by renewing only set of control information which may well be used next with the fixed information among those control information that must be renewed according to the access result. CONSTITUTION:A data base control part 33 first performs the renewal processing of a control table 34 in a command executing step 40. If 2 relative set types exist with a new record after it is decided that the using record is renewed with a new one in the next step 41, it is decide whether the next set type can be estimated or not in the step 43. In such a case, it is possible to estimate that the set type may most be used next in case said set type to be processed is specified with the actually executed command. Thus this set type is decided as the subject for renewal in the next step 44. The renewal is through with the information in the step 45. While the temporary renewal processing is carried out in the step 47 in case it is decided that the estimation of the set type is impossible in the step 43 and the renewing is unfinished.
