| الملخص: | Multitasking in both uniprocessor (multithreading) and multiprocessor (multiprocessing) systems have been attracted by many applications. Database systems are somewhat the most important in this regard, especially in centralized and humongous ones. Sometimes thousands, and maybe hundred of thousands of operations are sent to the transaction processing system per second. To handle this bottleneck some queries/updaters are executed concurrently. However, parallelism in such cases is extremely accurate based on the well-know restriction - locks. In this paper, we implement a lock approach based on a Boolean array (1D and 2D) and on the logical OR operation to specify which transactions can be executed in parallel. |
