Abstract: PURPOSE: The method for recomposing a free list in real time a DBMS is provided to enhance a reliability coefficient of the corresponding real time DBMS by moving conversely and confirming a free list flag in accordance with a position value of a tuple before driving a database, and recomposing a free list for successively connecting in accordance with a position value of a unused tuple. CONSTITUTION: A database file stored in a disk is loaded in a memory(S31). A corresponding real time DBMS sets a free list flag with respect to a tuple located in the last of a database table as "-1"(S32). The corresponding real time DBMS records a position value of a tuple located in the last of a database table in a first free list, and moves conversely and confirms a free list flag with respect to each tuple in accordance with a position value of a tuple(S33). The corresponding real time DBMS decreases the position value of a tuple as "1"(S34), and detects as to whether the position value obtained as a result thereof is "-1", that is, the value is an idle value(S35). If the position value obtained as a result thereof is "-1", a recomposing operation is closed(S39). If the position value obtained as a result thereof is not "-1", the corresponding real time DBMS detects as to whether a free list flag of a tuple indicated by the corresponding real time DBMS is "-1"(S36). If a free list flag of a tuple indicated by the corresponding real time DBMS is not "-1", the corresponding real time DBMS records the position value recorded in the current first free in a free list flag of the corresponding tuple(S37). The position value of the corresponding tuple is recorded in the first free(S38).
