Effects of shaping characteristics on the performance of nested transactions

چکیده
The nested transaction model was introduced to satisfy the requirements of advanced database applications. Moreover, it is currently the basic transaction model for new database applications like work¯ow systems and new database systems like mobile databases and object-relational databases. Though there are several performance evaluation studies of different concurrency control mechanisms in nested transactions, the effects of transaction parameters on the overall system performance have not received any attention. In this paper, we study the effects of transactions characteristics on system performance. We developed a detailed simulation model and conducted several experiments to measure the impact of transactions characteristics on the performance. First, the effect of the number of leaves on the performance of nested transactions is investigated under different shaping parameters. Also, effects of the depth of the transaction tree on the system performance are investigated.

متن کاملThe Importance of Leadership and Organizational Capacity in Shaping Health Workers’ Motivational Reactions to Performance-Based Financing: A Multiple Case Study in Burkina Faso
Background Performance-based financing (PBF) is currently tested in many low- and middle-income countries as a health system strengthening strategy. One of the main mechanisms through which PBF is assumed to effect change is by motivating health workers to improve their service delivery performance. This article aims at a better understanding of such motivational effects of PBF. In partic...

متن کاملNumerical Study of the tongue geometry effects on the cavitation and performance of a centrifugal pump in off-design conditions
In this study, the effects of the volute tongue geometry variation on the head, efficiency, velocity distribution and cavitation structure of a centrifugal pump in the steady flow behavior under off-design conditions have been investigated. Numerical simulation modeling based on the turbulence model with a hybrid grid is used to simulate the flow within the modeled pump. The flow is simulated ...
متن کاملA study on the effects of environmental factors on vegetative characteristics and corm yield of saffron (Crocus sativus)
Saffron (Crocus sativus L.) is one of the most important economical crops in Iran. The present study was conducted to evaluate the morphological characteristics and yield of saffron corms in six regions of Talesh city, Guilin province (Iran) with different altitudes. The studied regions were considered as treatments and the obtained data were analyzed based on a nested design. The results showe...
