data dictionary and transaction log
schedule is an interleaving of action from a set of transactions where the action of any transaction is in the original order.
DBMS (Database Management Systems) typically overcome TFBS (Transaction Failure Before System) by using transaction management techniques such as ACID properties (Atomicity, Consistency, Isolation, Durability). These ensure that transactions are either fully completed or reverted to their original state in case of failure, maintaining data integrity. Additionally, DBMS often implement logging and recovery mechanisms to help recover the database state in case of unexpected failures.
Durability is the part of recovery system ,it has response to recover the failure data,it also comes under transaction managment
