How does DB2 handle simultaneous access to data by multiple transactions?
- By allowing all transactions to access data simultaneously
- By randomly choosing which transaction gets access to data first
- By terminating transactions that attempt to access the same data
- Through techniques such as locking, timestamping, and multiversioning
DB2 handles simultaneous access to data by multiple transactions through various techniques such as locking, timestamping, and multiversioning. These techniques ensure that transactions can access and modify data without interfering with each other, thereby maintaining data consistency and integrity. Each technique has its advantages and is chosen based on factors such as transaction isolation level and performance requirements.
