Checkpoint is synonymous to Sync point, commit point or
point of integrity. Whenever a checkpoint is issued all the
records are committed and after a checkpoint system is in a
stable state. A checkpoint record entry is written to the
Log file and also generates a checkpoint ID which is used
for restarting the job from a particular checkpoint.
Database changes before the most recent checkpoint are not
reversed by backward recovery.
Database changes logged after the most recent checkpoint are
not applied to an image copy of the database during forward
recovery.
