Data Manipulation Facility
The Data Manipulation Facility (DMF) manages the DBMS Server interface to disk storage. In addition to managing all storage structures (hash, heap, ISAM, B-tree, BLOBs, and so on), DMF uses the logging and locking systems to control transaction processing and to handle concurrency issues. Included within DMF is a buffer manager that controls access to a cache (possibly shared) of database pages.
