This paper proposes a novel scheduling algorithm called Query-based Scheduling Algorithm(QSA) to address the issue of real-time query processing in on-demand data broadcast environments.
现有的实时数据广播研究中，只考虑了具有截止期约束的单个数据请求的调度问题，而支持实时查询处理的数据广播技术尚未得到足够的关注。

On-line data centers are increasing their capacity to deal with this increased demand for processing power, communication speeds and digital storage capacity but despite the increases in efficiency of enterprise equipment and software there is a price to pay for universal connectivity and general on-line resources.
