中文摘要 | 對於以lock為基礎的R-tree共時控制運算法則,用模擬方法來評估這些共時控制 運算法則之績效。評估準則為throughput和response time,為了要回答一個共時控制運算法 則其續效何以比另一個共時控制運算法則好,我們用五個因子來解釋,其中有三個因子屬於 靜態性質,另兩個因子則屬於動態性質。 |
英文摘要 | Looking based concurrency control protocols are added into the access methods of R-tree. To evaluate the performance of these concurrency control algorithms (CCAs), the performance of CCA is evaluated by means of simulation. The evaluated criteria are the response time and throughput of a CCA. To explain why one CCA has better (or worse) performance than another CCA, five general and logical-oriented, three static and two dynamic, factors are presented. The static factors can explain the structural properties of a CCA, and the dynamic ones can be used to explore a CCA's run-time properties. With these factors, the performance of a CCA can be well explored and explained. |
