Solution
The primary role of the transaction manager in query processing is to ensure the atomicity and consistency of database transactions. This means that the transaction manager is responsible for making sure that all database transactions are processed as a single unit of work, and that the database remains in a consistent state before and after each transaction. This involves managing the concurrency of transactions, handling transaction failures, and providing isolation between concurrent transactions.
