How a database can be recovered from failed transaction?
A database can be recovered from a failed transaction using a method called rollback, which reverts the database to its last consistent state before the transaction began. This is typically achieved through a transaction log that records all changes made during transactions. If a failure occurs, the database management system (DBMS) uses the log to undo any changes made by the incomplete transaction, ensuring data integrity. Additionally, in some systems, checkpointing can be used to minimize the amount of data that needs to be rolled back.
What is a transaction processing system?
Transaction processing system are operational level systems at the bottom of the pyramid.
Why are transaction important limit of operation in a dbms?
Transaction limits in a Database Management System (DBMS) are crucial because they ensure data integrity and consistency during operations. By defining a set of operations that must either all succeed or all fail, transactions help prevent partial updates that could lead to data corruption. Additionally, they support concurrency control, allowing multiple users to interact with the database without conflicts. Overall, transactions are fundamental for maintaining reliable and accurate data in a multi-user environment.

How DBMS overcomeTFBS?
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.
