Explanation of Multiple Granularity with suitable example
WebLock granularity If one application holds a lock on a database object, another application might not be able to access that object. For this reason, row-level locks, which minimize the amount of data that is locked and therefore inaccessible, are better for maximum concurrency than block-level, data partition-level, or table-level locks.
