ACID properties for MDC3 data stores?

• A. High Availability
• B. Data Encryption
• C. Scalability
• D. Atomicity, Consistency, Isolation, Durability; Ensure Reliable Transactions

Answer: (D)

ACID properties describe how transactions should behave to keep data correct and reliable. Atomicity means a transaction is all-or-nothing: either every operation within the transaction completes, or none do, so partial updates don’t leave the system in an inconsistent state. Consistency ensures that each transaction takes the database from one valid state to another, enforcing the defined rules and constraints. Isolation means concurrent transactions don’t interfere with each other; the outcome looks as if transactions were processed one at a time, preventing dirty reads and related anomalies. Durability guarantees that once a transaction is committed, its changes persist even if the system crashes, typically via durable logging and recovery mechanisms.

If you’re considering what MDC3 data stores aim to provide with respect to reliable transactions, the ACID properties are the fundamental framework for that guarantee. High Availability, Data Encryption, and Scalability are important features in their own right, but they describe uptime, security, and growth handling rather than the precise guarantees about transactional correctness and persistence that ACID defines.
