What does "transaction" mean in programming?
transaction is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A sequence of database operations that are executed as a single unit. Either all operations succeed (commit) or none of them take effect (rollback). Transactions ensure data consistency when multiple changes must happen together.
Example
"Wrap the payment and inventory update in a transaction so neither change is saved if one fails."
