Patent ID: 7228323

Claim:
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 associated with a second physical storage space that is smaller than the first physical storage space, the method comprising: receiving a non-zero user-specified deviation metric related to the raw set of electrical power generation process data; receiving the raw set of electrical power generation process data, the raw set comprising at least three data points; automatically defining a first artificial data point by adding the non-zero user-specified deviation metric to an ordinal value of a second data point; automatically defining a second artificial data point by subtracting the non-zero user-specified deviation metric from an ordinal value of a third data point; automatically calculating a first connecting line slope, the first connecting line defined by a first data point and the first artificial data point; automatically calculating a second connecting line slope, the second connecting line defined by the first data point and the second artificial data point; and if the second connecting line slope is greater than the first connecting line slope, automatically causing a point related to the third data point to be stored in a compressed set at least partially representative of the raw set, the compressed set stored in an Oracle table on a memory device.
