Transactions: All-or-Nothing Database Changes
Some operations involve several steps that must all succeed together, or none at all. Moving money between two accounts is the classic example: debiting one without crediting the other would be a disaster.
A database transaction guarantees this all-or-nothing behaviour, keeping your data consistent even when something fails halfway through.
Why It Protects Your Data
Inside a transaction, every change is provisional until the whole thing is confirmed. If any step fails — a crash, an error, a timeout — the database undoes all of it, leaving your records exactly as they were.
- No half-finished orders or split payments.
- Stock and accounts stay in agreement.
- A crash mid-operation leaves no mess to clean up.
Where We Use Them
We wrap any operation that touches several related records in a transaction — placing an order, transferring funds, updating linked accounts. The cost is negligible and the protection is enormous: your data can never be left in a contradictory, half-updated state, no matter what goes wrong partway through.
| Step | Without transaction | With transaction |
|---|---|---|
| Debit account A | Done | Provisional |
| Crash before crediting B | Money lost | Everything undone |
| Result | Inconsistent data | Safe and consistent |
