Disclosed is a computer implemented method of determining an aggregated web analytics value. A first data storage medium stores a sequence of episodic values, each associated with a respective time interval. A second data storage medium stores a sequence of aggregate values, each aggregating an equal number of the episodic values. Further aggregates are stored and provided in a like manner, until an additional sequence of higher level aggregate values cannot be created using the same base number. When a request for an aggregate value over a range of episodic values is received, the system queries the storage mediums in a parallel operation, retrieving as little aggregated values and episodic values needed to compute the requested value. |
