- 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績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: Locking based concurrency control protocols are added into the access methods of R-tree. To evaluatethe performance of these concurrency control algorithms (CCAs), the performance of CCA is evaluatedby means of simulation. The evaluated criteria are the response time and throughput of a CCA. To explainwhy 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 propertiesof 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.
