ABSTRACT:
A method, system and article of manufacture for processing abstract queries and, more particularly, for generating input to statistical analysis routines. One embodiment comprises receiving an abstract query including a measurement field and a chronological reference condition. The abstract query is transformed into an executable query which is executed by a query engine, whereby result data is determined including an available measurement value for the measurement field. The available measurement value was taken at a point in time different from a point in time that satisfies the chronological reference condition. The method further comprises determining a variance value corresponding to a time variance between the point in time that satisfies the chronological reference condition and the other point in time at which the available measurement value was taken. As a result set for the abstract query, the available measurement value and the variance value are returned.
