How do transactions affect concurrent operations in a database? Transactions impact concurrent operations by introducing locking mechanisms to ensure that multiple transactions don't interfere with each other and cause inconsistent data. This
ffects concurrency in several ways:
- Locking: Transactions may lock rows or tables to prevent conflicting changes,
leading to possible delays for other transactions.
- Deadlocks: When two or more transactions are waiting for each other to release
locks, causing a cycle of dependency. This can be automatically detected and
resolved by the DBMS.
