The executions of transactions are strict if read and write operations on an object are delayed until
all transactions that previously wrote that object have either committed or aborted. Explain how
the locking rules in Figure 16.16ensure strict executions.
What will be an ideal response?
If a previous transaction has written a data item, it holds its locks until after it has committed, therefore no other
transaction may either read or write that data item (which is the requirement for serial executions).
