Which SQL component is used for managing database transactions?

• A. Transaction Control Language
• B. DDL
• C. DML
• D. DRL

Answer: (A)

Managing transactions in SQL is all about controlling when a set of operations becomes permanent and how to undo them if something goes wrong. The part of SQL that handles this is Transaction Control Language. It includes commands that define the boundaries of a transaction and its outcome, such as COMMIT to finalize changes, ROLLBACK to undo them, and SAVEPOINT to mark a point to which you can roll back, along with SET TRANSACTION to adjust properties like isolation level. This set of commands specifically focuses on the transactional behavior of the database, separate from altering structure or manipulating data. DDL defines or changes the database schema, DML changes the actual data, and DRL isn’t a standard SQL component. So, for managing database transactions, Transaction Control Language is the right choice.
