What are the Common Techniques for Concurrency Control?
Several techniques are employed for concurrency control in business:
Locking Mechanisms: This involves placing locks on data items during a transaction to prevent other transactions from accessing the same data concurrently. Timestamp Ordering: Transactions are assigned timestamps, and their execution is scheduled based on these timestamps to avoid conflicts. Optimistic Concurrency Control: Transactions proceed without restrictions but are validated before committing to ensure no conflicts occurred. Multiversion Concurrency Control (MVCC): Multiple versions of data items are maintained to allow concurrent read and write operations without interference.
