ABSTRACT:
A database management system incorporating an intermediate level of storage medium. Software of the DBMS controls the transfer of data between a primary, secondary and intermediate storage mediums. This transfer is under control of the DBMS and is not transparent to the DBMS. The intermediate storage medium has an access time that is shorter than the access time of the secondary storage medium. During operation of the DBMS, data is read from the secondary storage medium and held in the primary storage medium until the storage medium is full. Thereafter, as additional data is read by the DBMS from the database stored on the secondary storage medium, data is transferred to the intermediate storage medium under control of the DBMS, thus preserving the benefit of having the data read into the primary storage medium.
