摘　　要：随着移动智能终端处理能力和存储技术的快速发展,面向移动智能终端的数据库技术与应用成为近年来的研究热点.但是,移动智能终端的电能极其有限,已成为阻碍移动终端应用发展的关键因素.而现有的面向移动智能终端的嵌入式数据库系统在查询处理等方面缺乏对能耗问题的考虑.针对移动智能终端数据库应用提出的能耗有效查询处理需求,提出并设计了一个用于测试移动智能终端数据库查询能耗的工具———TPCDroid.TPCDroid以TPC-H为基准设计了面向移动智能终端能耗测试的查询集,选择了一批有代表性的查询请求作为测试负载,并建立了基于Android系统的测试平台.TPCDroid可以测试不同类型的查询请求的能耗和性能,可以作为面向移动智能终端的查询处理能耗有效性测试平台,从而推动嵌入式和移动数据库技术的进一步发展.With the rapid development of the processors and storage technologies on smart devices, developing database applications for smart devices has been a hot research topic in recent years. However,the low power capability of smart devices has been a critical factor cumbering the future development of smart applications.Furthermore,current embedded database systems on smart devices lack the consideration on energy efficiency.Therefore,aiming at solving the energy-efficient query processing issue in smart database applications,in this paper we present and implement TPCDroid,a benchmark tool to measure the energy consumption of database queries over smart devices.TPCDroid is built on the TPC-Hbenchmark.We select some typical queries as the testing queries,and implement a measurement tool on Android.TPCDroid can measure the energy consumption as well as performance metrics for different queries.It can be used as a basic benchmark platform for energy efficiency of smart applications,and thus promote the development of embedded databases as well as mobile databases.
