Abstract: The present invention relates to the field of information system technology. More particularly, the present invention relates to methods and systems for Real-Time information processing, including Real-Time Data Warehousing, using Real-Time in-formation aggregation (including calculation of the performance indicators and the like) based on continuous homomorphic processing, thus preserving the linearity of the underlying structures. The present invention further relates to a computer program product adapted to perform the method of the invention, to a computer-readable storage medium comprising said computer program product and a data processing system, which enables Real-Time information processing according to the methods of the invention.
