A system, method, and a computer program product for caching multi-dimensional data based on an assumption of locality of reference. A user sends a query for data. A described compilation module converts the query into a set of cubelet addresses and canonical addresses. In the described embodiment, if the data corresponding to the cubelet address is found in a data cache, the data cache returns the cubelet, which may contain the requested data and data for "nearby" cells. The data corresponding to the canonical addresses is extracted from the returned cubelet. If the data is not found in a data cache, a fault handler queries a back-end database for the cubelet identified by the cubelet address. This cubelet includes the requested data and data for "nearby" cells. The requested data and the data for "nearby cells" are in the form of values of measure attributes and associated canonical addresses. The returned cubelet is then cached and the data corresponding to the canonical addresses is extracted.
