DESIGN METHOD OF QUERY CLASSIFICATION COMPONENT IN MULTI-LEVEL DBMS

摘要

A design method for a query classification component in a multi-level DBMS(Database Management System) is provided to increase the use rate of a snapshot by dividing a predicate of an inputted query into a memory part and a disk part. A designing method for a query classification component in a multi-level DBMS includes the steps of: determining whether an execution plan used in a query process is inputted(S10); designing the query classification component in order to print a corresponding predicate and a location for each table together with the execution plan, if the execution plan is inputted(S1000); and passing the printed corresponding predicate and the location for each table to each storage manager and processing the corresponding data by each storage manager(S2000).
