What does ACID stand for in relation to ensuring data integrity?

ACID is a set of properties that guarantee that database transactions are processed reliably and ensure data integrity. Each aspect of ACID plays a critical role in maintaining the accuracy and reliability of data in systems that handle transactions.

The term "Atomicity" refers to the principle that each transaction is treated as a single, indivisible unit that either completely succeeds or completely fails. This ensures that partial transactions do not occur, preventing corruption of data.

"Consistency" ensures that a transaction brings the database from one valid state to another valid state without violating any database rules. It helps maintain the integrity of the data.

"Isolation" is the property that ensures that transactions are executed independently of one another. This allows for concurrent execution of transactions without interference, which is essential for maintaining data integrity in multi-user environments.

"Durability" guarantees that once a transaction has been committed, it remains so, even in the event of a system failure. This means that completed transactions will not be lost, thus ensuring that the data remains accurate and reliable over time.

These four principles work together to assure that database transactions are processed in a reliable manner, ultimately supporting the overall aim of ensuring data integrity in computing environments.
