Question

This specifies that READ and WRITE transaction operations have ended and marks the end of transaction execution. However, at this point it may be necessary to check whether the changes introduced by the transaction can be permanently applied to the database (committed) or whether the transaction has to be aborted because it violates serializability. True or False?

Answer 1

The statement is true and pertains to the decision to commit or abort a transaction in a database after READ and WRITE operations, depending on serializability and constraints.

Step-by-step explanation:

The statement addresses the concept known as transaction commitment in the realm of databases, particularly in the context of database management systems (DBMS). The statement is true. It explains that once READ and WRITE operations are completed, the transaction reaches a point where it must be determined whether the changes can be committed and thus made permanent in the database, or if the transaction must be rolled back, often due to issues with serializability or other constraint violations.
