Description: Non-exclusive locks are a concurrency control mechanism in databases that allows multiple transactions to read data simultaneously without blocking each other. Unlike exclusive locks, which prevent other transactions from accessing the same data while it is in use, non-exclusive locks facilitate smoother and more efficient access to information. This type of lock is fundamental in environments where data reading is more frequent than writing, as it allows multiple users to perform queries without interference. Non-exclusive locks are essential for maintaining data integrity and consistency in database systems, especially in high-performance applications where latency must be minimized. By allowing transactions to read data without restrictions, the overall system performance is optimized, resulting in a more agile and responsive user experience. However, it is important to manage these locks properly to avoid consistency issues, such as dirty reads, where one transaction may read data that is being modified by another transaction. In summary, non-exclusive locks are a key tool in optimizing concurrent access to database resources while balancing performance and data integrity.
