Lec-84: Conflict Serializability | Precedence Graph | Transaction | DBMS

👉Subscribe to our new channel: / @varunainashots
A schedule is called conflict serializable if it can be transformed into a serial schedule by swapping non-conflicting operations. Conflicting operations: Two operations are said to be conflicting if all conditions satisfy: They belong to different transactions. They operate on the same data item.
