INQUIRY PROCESSING SYSTEM FOR DISTRIBUTED DATA BASE SYSTEM

摘要

PURPOSE:To speed up inquiry processing by controlling the conversion of data according to information to show need or needlessness in the case where data base inquiring data is edited by a data converting means when data base inquiry is inputted. CONSTITUTION:The information to show the need or the needlessness of the data conversion in each level is set by using a mapping level adding means. Namely, a data conversion level in each level is set by using the mapping level adding means, and when the data base inquiry is inputted, at the time of the editing of the data base inquiring data, the data converting means converts the data according to a mapping level, and transfers it to an origin of a request. Thus, needless data conversion can be excluded, and the speedup of the inquiry processing can be attained.
