Analysis and processing method of a data stream based on wavelet

The steaming data can continuously arrive with great speed and great capability and its kernel is to design an effective single data set scanning arithmetic, continually update a synopsis data structure in the memory space that is much less than data scale,which makes an approximate query result can be quickly achieved at any time according to the structure. This paper employs the wavelet method to achieve the sampling of data streaming, and makes an query of data streaming.
