Abstract:
1. A method for storing a data series at multiple resolutions in a computer-readable data storage medium, wherein data of the data series are sequential data from a sensor, the method comprising: receiving a first time series data value of the data series, the first time series data value associated with a first timestamp; identifying a first storage element from a series of storage elements in the computer-readable data storage medium that corresponds to the first time series data value based on the first time stamp, wherein each storage element of the series of storage elements represents a different segment of time; determining a first aggregate value, wherein the first aggregate value is equal to the sum of the first time series data value and a first stored time series data value, the first stored time series data value stored in the first storage element, and wherein the first stored time series data value is a first previously stored aggregate value associated with previously received data of the data series; replacing the first stored time series data value with the first aggregate value; adding the first aggregate value to a first combined data value stored in a fifth storage element in the series of storage elements in the computer-readable data storage medium, the first combined data value including the first aggregate value and a second aggregate value; receiving a second time series data value of the data series, the second time series data value associated with a second timestamp; identifying a second storage element from the series of storage elements that corresponds to the second time series data value based on the second time stamp; determining the second aggregate value, wherein the second aggregate value is equal to the sum of the second time series data value and a second stored time series data value, the second stored time series data value stored in the second storage element, and wherein the second stored time series data value is a second previously stored aggregate value associated with previously received data of the data series; replacing the second stored time series data value with the second aggregate value; adding the second aggregate value to the first combined data value stored in the fifth storage element in the series of storage elements in the computer-readable data storage medium; receiving a third time series data value of the data series, the third time series data value associated with a third timestamp; identifying a third storage element from the series of storage elements that corresponds to the third time series data value based on the third timestamp; determining a third aggregate value, wherein the third aggregate value is equal to the sum of the third time series data value and a third stored time series data value, the third stored time series data value stored in the third storage element, and wherein the third stored time series data value is a third previously stored aggregate value associated with previously received data of the data series; replacing the third stored time series data value with the third aggregate value; adding the third aggregate value to a second combined data value stored in a sixth storage element in the series of storage elements in the computer-readable data storage medium, the second combined data value including the third aggregate value and a fourth aggregate value; receiving a fourth time series data value of the data series, the fourth time series data value associated with a fourth timestamp; identifying a fourth storage element from the series of storage elements that corresponds to the fourth time series data value based on the fourth timestamp; determining the fourth aggregate value, wherein the fourth aggregate value is equal to the sum of the fourth time series data value and a fourth stored time series data value, the fourth stored time series data value stored in the fourth storage element, and wherein the fourth stored time series data value is a fourth previously stored aggregate value associated with previously received data of the data series; replacing the fourth stored time series data value with the fourth aggregate value; adding the fourth aggregate value to the second combined data value stored in the sixth storage element in the series of storage elements in the computer-readable data storage medium; storing the first, second, third, and fourth aggregate values at a first resolution in the computer-readable data storage medium; and storing the first and second combined data values at a second resolution in the computer-readable data storage medium.
