Question

although the DBMS is designed to recover a database to a previous consistent state when an interruption prevents the completion of a required set of transactions, the transactions themselves are defined by the end user or programmer and must be semantically correct. True or false

Answer 1

The statement is true; the DBMS can recover a database to a consistent state, but transactions must be semantically correct as defined by end users or programmers.

Step-by-step explanation:

The statement is true. While a Database Management System (DBMS) is equipped with recovery mechanisms to restore a database to a previous consistent state following an interruption during transactions, it is the responsibility of end users or programmers to ensure that the transactions themselves are semantically correct.

This means that the series of operations that constitute a transaction must make sense in the context of the business logic they are intended to support.

The DBMS does not generate the logic of the transactions; it merely ensures that transactions are processed reliably, maintaining integrity, consistency, and in the event of a failure, the ability to recover to a prior state without loss of data.
