Database Concurrency
Database concurrency is a concept in database management that deals with the simultaneous execution of multiple transactions or operations on a database without compromising data integrity. It ensures that multiple users or applications can access and modify data concurrently while maintaining consistency, isolation, and reliability through mechanisms like locking, timestamps, and multi-version concurrency control (MVCC). This is crucial for high-performance systems where data must be available and accurate under heavy load.
Developers should learn database concurrency to build scalable and efficient applications that handle multiple users or processes accessing data at the same time, such as in e-commerce platforms, banking systems, or real-time analytics. It prevents issues like lost updates, dirty reads, and deadlocks, ensuring data accuracy and system reliability in environments with high transaction volumes.
