Question 1

Accepted Answer

A) True 
 B)False  False

Question 2

What is transaction transparency? What are some of the basic concepts that one should know to understand how transactions are managed in a distributed database management system (DDBMS)?

Accepted Answer

Transaction transparency is a DDBMS property that ensures database transactions will maintain the distributed database's integrity and consistency. It should be remembered that a DDBMS database transaction can update data stored in many different computers connected in a network. Transaction transparency ensures that the transaction will be completed only when all database sites involved in the transaction complete their part of the transaction.
Distributed database systems require complex mechanisms to manage transactions and ensure the database's consistency and integrity. To understand how the transactions are managed, the basic concepts governing remote requests, remote transactions, distributed transactions, and distributed requests should be known.
