- A database transaction is a way to ‘link’ multiple queries together as if they were executed as a single unit. This allows queries that need to succeed as a group to either all succeed or all fail.
- Using transactions has the following steps:
- Signify the start of a transaction.
- Run the queries comprising the transaction ‘unit’.
- If ALL queries are successful, commit ALL of the query results.
- If an error occurs in ANY query, rollback the results of ALL queries that were part of the transaction unit.
