Analog data is compressed by processing certain data from data storage and interpolating data between data points which fall within an acceptable error range. Data points are compressed by modifying or eliminating data depending upon the slope relationship of a stored data point to artificial data points, which are representative of the range of accepted deviations from the original data point.

Analog data compression

Certain exemplary embodiments comprise a method for transforming a raw set of electrical power generation process data associated with a first physical storage space into a representation of the raw set. The representation of the raw set can be associated with a second physical storage space that is smaller than the first physical storage space. The method can comprise receiving a non-zero user-specified deviation metric relating to the raw set of electrical power generation process data. The method can comprise automatically calculating a deviation measure of at least three data points from the raw set, the at least three data points comprising an opposing pair of end points. The method can comprise automatically comparing the deviation measure to the deviation metric. The method can comprise automatically deleting all data points intermediate to the opposing pair of end points if the deviation measure does not exceed the deviation metric. The method can comprise automatically storing the opposing pair of end points in a compressed set at least partially representative of the raw set. The compressed set can be stored in an Oracle table on a memory device.
