Expert Solution

Step 1: The Crucial Role of a Global Transaction Manager in Ensuring Data Consistency in DDMS

Distributed Database Management Systems (DDBMS) have become a crucial infrastructure in the field of modern data management, allowing for the management of enormous amounts of data across numerous nodes or databases in a distributed environment. A vital element known as the Global Transaction Manager (GTM) is instrumental in preserving the consistency and integrity of data within this complicated environment. The GTM acts as the transaction orchestrator, ensuring data coherence between dispersed nodes and the ACID qualities (Atomicity, Consistency, Isolation, Durability).
