What aspect of data management does ACID focus on?

• A. Network configurations and deployment
• B. Transaction principles ensuring reliability
• C. Server performance optimization
• D. User interface design

Answer: (B)

ACID refers to a set of properties that ensure reliable processing of database transactions. The acronym stands for Atomicity, Consistency, Isolation, and Durability. Each component plays a vital role in maintaining the integrity of data during transactions. Atomicity guarantees that a transaction is treated as a single unit that either fully occurs or does not occur at all, preventing any partial updates that could lead to data inconsistency. Consistency ensures that a transaction moves the database from one valid state to another, helping maintain the integrity of the data according to defined rules. Isolation allows concurrent transactions to operate without interfering with each other, thus avoiding issues such as dirty reads or lost updates. Lastly, Durability ensures that once a transaction has been committed, it remains so, even in the event of a system failure. This focus on these principles is essential for applications that require reliable and consistent data handling, making option B the appropriate choice, as it encompasses the core purpose of ACID in data management. The other options, while relevant to broader aspects of data management, do not pertain to the specific transaction principles that ACID addresses.
