What are some real-world examples of data consistency?

Data consistency ensures that data remains accurate and reliable across different systems. Examples include banking transactions, where account balances must be consistent after deposits or withdrawals, and e-commerce platforms, where inventory levels must reflect real-time stock availability.

Can you explain how data consistency is maintained in banking?

In banking, data consistency is maintained through ACID properties in transactions, ensuring that all operations are completed successfully or none at all. This prevents issues like double spending.

What happens if data consistency is not maintained?

If data consistency is not maintained, it can lead to errors such as incorrect account balances, lost transactions, or inventory discrepancies, which can severely impact business operations and customer trust.

Are there specific technologies used to ensure data consistency?

Yes, technologies like distributed databases, data replication, and consistency protocols such as Paxos or Raft are commonly used to ensure data consistency across systems.
