            • Data streaming, commonly seen in the forms of audio and video streaming, is when a multimedia file can be played back without being completely downloaded first. Most files, like shareware and software updates that you download off the Internet, are not streaming data. However, certain audio and video files like Real Audio and QuickTime can be streaming files. With a fast Internet connection, you can usually stream live audio or video to your computer as fast or faster than you can listen or watch the content. Southern Rural Development Center
          • Example sentence(s)
            • Data streaming requires some combination of bandwidth sufficiency and, for real-time human perception of the data, the ability to make sure that enough data is being continuously received without any noticeable time lag. - SearchNetworking.com
            • Efficient and robust data streaming services are a critical requirement of emerging Grid applications, which are based on seamless interactions and coupling between geographically distributed application components. - Portal
            • A practical data streaming service must, therefore, be largely selfmanaging, i.e., it must dynamically detect and respond, quickly and correctly, to changes in application behaviour and state of the Grid. - A Self-Managing Wide-Area Data Streaming using Model-based Online Control

          • Definition(s)
            • 数据流是数据在稳定的高速传输，这种速率足以支持类似高清电视（HDTV）或者在一台计算机内连续地将备份拷贝到工作流的存储媒介中这类的应用程序。数据流需要足够的带宽,实时的人类对数据的感知，确保足够的数据能够流畅地接受而没有明显的时间滞后的能力。 数据流 - by Yurek
          • Example sentence(s)
            • 有关流数据分析与管理的研究是目前国际数据库研究领域的一个热点.流数据的特点是数据持续到达,且速度快、规模宏大;其研究核心是设计高效的单遍数据集扫描算法,在一个远小于数据规模的内存空间里不断更新一个代表数据集的结构--概要数据结构,使得在任何时候都能够根据这个结构迅速获得近似查询结果.将主要采用小波方法对数据流的采样加以实现,并对数据流进行查询 - 小波方法在数据流中的应用 by Yurek
            • 数据流看作是以数据到达时间为序的一个时间序列，借鉴传统时间序列分析技术探讨了连续聚集查询的未来聚集值预测问题，但由于数据流序列与传统时间序列在时间间隔和数据集的处理上存在很大差别，于是采用流滑动窗口技术加以处理。其次，针对目前数据流聚集查询预测领域已有的一些研究结果都未考虑流数据内在的复杂非线性动力学特征对预测的影响问题，该算法又利用了混沌理论中的局域预测思想解决了这一不足。实验结果表明，利用该算法进行预测具有很好的准确性 - 一种基于混沌理论的数据流连� by Yurek
