Question

A schedule S is ___ if, for every transaction T participating in the schedule, all the operations of T are executed consecutively in the schedule.

Answer 1

A schedule S is serialized if all operations of a transaction are executed consecutively

Step-by-step explanation:

A schedule S is serialized if, for every transaction T participating in the schedule, all the operations of T are executed consecutively in the schedule. In other words, a serialized schedule ensures that no two transactions are executing their operations concurrently. This helps maintain data consistency and avoid conflicts that may arise due to concurrent execution.

For example, consider a banking system where two transactions T1 and T2 involve transferring funds from one account to another. If T1 and T2 are not serialized, it is possible that the final balance could be incorrect if they execute concurrently. By ensuring that all operations of T1 and T2 are executed consecutively, a serialized schedule guarantees correct results.

Serialization is an important concept in databases and transaction management, as it helps maintain data integrity and prevent unpredictable behaviors.
