Transaction Management Overview
... Steal approach: the changes made to an object O by a transaction T may be written to disk before T commits. This arises when the buffer manager decides to replace the frame containing O by a page (belonging to a different transaction) from disk. Force approach: Force all writes of a committed transa ...
