Distinguish between a database lockout and a deadlock
To achieve data currency, simultaneous access to individual data elements or records by multiple users needs to be prevented. The solution to this problem is a database lockout, which is a software control that prevents multiple simultaneous accesses to data. A deadlock occurs when multiple users seeking access to the same set of records lockout each other. As a result, the transactions of all users assume a wait state until the locks are removed. A deadlock is a permanent condition that must be resolved by special software that analyzes each deadlock condition to determine the best solution.
