Can you explain how transaction logging works in databases?
Sure! Transaction logging is a mechanism that records all changes made to a database. It helps in recovery and maintaining data integrity.
What are the benefits of using transaction logs?
The main benefits include data recovery, auditing changes, and ensuring ACID properties, which guarantee reliable transactions.
How does it help in data recovery?
In case of a failure, transaction logs can be used to restore the database to its last consistent state by replaying or rolling back transactions.
Are there different types of transaction logging?
Yes, there are mainly two types: physical logging, which records changes at the storage level, and logical logging, which records changes at the application level.
