A Per-object Based Hybrid Concurrency Control
Existing concurrency control algorithms do not well conform to various environments, in the performance perspective. Each algorithm has some assumption on the conflict characteristic of its execution environment, and itsperformance degrades when the assumptionfails. rl per-object hybrid scheme integrating two-phase locking algorithm with parallel validation technique is presented to solve this problem. Read and write accesses on each database object are controlled by one algorithm at a time. This controlling algorithm can alter during transactions are running, in order to enhance the overall ?stem performance. In the simulation studv, proposed scheme with the proposed algorithm alteration strategp is shown to well conform to various execution environments, better than both two-phase locking algorithm and parallel validation technique.
