What are some real-world examples of data consistency?

Data consistency ensures that data remains accurate and reliable across different systems. For example, in banking, when you withdraw money from an ATM, the balance should immediately reflect that change across all platforms, including online banking.

Can you give me another example?

Sure! In e-commerce, when a customer places an order, the inventory must update in real-time to prevent overselling. This ensures that the stock levels are consistent across the website and the warehouse.

What happens if data consistency is not maintained?

If data consistency is not maintained, it can lead to errors such as double bookings in travel systems or incorrect account balances in banking, which can severely impact customer trust and business operations.

How do companies ensure data consistency?

Companies use various methods like database transactions, data replication, and consistency models such as eventual consistency to ensure that data remains consistent across all platforms.
