Discuss the ACID properties in database management systems. What do each of the properties (Atomicity, Consistency, Isolation, Durability) entail, and why are they crucial for reliable transaction processing? Provide examples where applicable.
Focus on defining each property clearly and explaining its significance in maintaining data integrity and reliability in relational databases. Include real-world scenarios to illustrate your points.
Ensures that a transaction is treated as a single unit, which either fully completes or does not happen at all. This prevents partial updates to the database.
Guarantees that a transaction will bring the database from one valid state to another, maintaining all predefined rules, including constraints and cascades.
Ensures that transactions occur independently without interference from concurrent transactions, which helps maintain data accuracy.
Guarantees that once a transaction has been committed, it will remain so, even in the event of a system failure, ensuring data permanence.
