When a transaction starts in MVCC, the DB gives it a unique, always-increasing transaction ID (txid). Any data with a txid higher than yours is invisible to you. Any data marked as deleted by a txid smaller than yours is visible until you finish. #ACIDTransactions

To implement Snapshot Isolation, DBs use MVCC (Multi-Version Concurrency Control). MVCC means the database keeps multiple versions of an object, tagged with the ID of the transaction that created them. #ACIDTransactions

Most DBs prevent dirty writes by using row-level locks. The second writer must wait until the first one commits or aborts. #ACIDTransactions
