Some operating systems perform buffered I/O. In this scheme, an output request is accepted from a user, and the user is informed of the normal I/O completion. However, the actual physical write operation is performed later, at a time convenient to the operating system. Discuss the effect of buffered I/O on integrity in a DBMS.
What will be an ideal response?
Because of buffered I/O, the DBMS will think a write has been completed when in fact it may not have been.
