SQL Design Flaws Causing Concurrency Issues Concurrency is a critical aspect of database design that cannot be overstated in multi user environments.
In such scenarios, concurrent access to data can lead to issues like deadlocks, lost updates, and inconsistent results.
Common SQL design flaws contributing to concurrency issues include the lack of transactions and poor indexing. Transactions provide atomicity, ensuring that either all changes or none take effect in case of an error.
