How do I implement optimistic concurrency in my application?
Optimistic concurrency control allows multiple transactions to occur without locking resources. You can implement it by using versioning.
Can you explain how versioning works in this context?
Sure! Each record has a version number. When updating, you check if the version matches the current one. If it does, you proceed; if not, you reject the update.
What happens if two users try to update the same record at the same time?
In that case, the first update will succeed, and the second will fail due to a version mismatch. The second user will need to reload the data.
Are there any libraries or frameworks that can help with this?
Yes, many frameworks like Entity Framework for .NET or Hibernate for Java support optimistic concurrency out of the box.
