Concurrency Error Prevention

 

Concurrency can be understood as a moment when multiple users access the same item in the system (a sample, material, test, etc.) at once. ExeVision works to prevent saving errors during concurrency.

When one user has made changes to a system item, other users who have accessed the item at the same time are prevented from saving their changes to that item.

If, for example, a user modifies a test which another user was modifying at the same time, the user who saves first will have their changes recorded. The user who saves last will receive a dialog alerting them that someone else has modified the test and that their changes cannot be saved.
