Q7. In databases, a sequence of database operations that satisfies the ACID properties is called:

The sequence of database operations that satisfies the ACID properties is called a transaction. ACID stands for Atomicity, Consistency, Isolation, and Durability, which are the key properties that ensure reliable processing of database transactions.

1. Atomicity guarantees that all operations in the transaction are completed successfully as a single unit. If any operation fails, the entire transaction fails.

2. Consistency ensures that a transaction can only bring the database from one valid state to another, maintaining all predefined rules, including integrity constraints.

3. Isolation ensures that transactions occur independently from one another. The operations of one transaction do not affect the operations of concurrent transactions.

4. Durability guarantees that once a transaction has been committed, it will remain so, even in the event of a system failure.

Thus, when multiple database operations are grouped into a sequence that adheres to these properties, it is termed a transaction.
