What does "durability" mean in programming?
durability 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
In databases (ACID), durability guarantees that a committed transaction persists even if the system crashes. More broadly, durability describes how long a system or its data survives failures, power loss, or time.
Example
"Durability in PostgreSQL means a committed transaction survives a power failure — data is written to disk."
