ACID Transactions
ACID Transactions are a set of properties that guarantee reliable processing of database transactions. The acronym stands for Atomicity, Consistency, Isolation, and Durability, which ensure that database operations are processed reliably even in the event of errors, power failures, or concurrent access. This concept is fundamental to maintaining data integrity in relational databases and other transactional systems.
Developers should learn and use ACID transactions when building applications that require strict data integrity, such as financial systems, e-commerce platforms, or healthcare records where incorrect or partial data updates could cause serious issues. They are essential for ensuring that critical operations like money transfers or inventory updates either complete fully or roll back completely, preventing data corruption and maintaining consistency across the database.
