Transactions in Computer Science

A transaction in computer science is a series of operations performed as a single, cohesive unit, ensuring data integrity. Think of it like a bank transfer: either all steps—debiting one account and crediting another—complete successfully, or none do, preventing errors like money disappearing. Transactions follow the ACID properties: Atomicity (all or nothing), Consistency (valid data), Isolation (independent processes), and Durability (permanent results). This system guarantees that even if there's a failure during processing, the data remains accurate and reliable, enabling safe and consistent interactions with databases and computational tasks.
