Database concurrency

Database concurrency refers to the ability of multiple users or applications to access and modify a database at the same time without interfering with each other. Imagine a shared online document where several people can edit it simultaneously; they must coordinate to avoid overwriting each other's changes. In databases, mechanisms like locking, transactions, and isolation levels help manage this process, ensuring data integrity and consistency. Effective concurrency allows for better performance and user experience, as it supports real-time collaboration while preventing conflicts and errors.
