A risk analysis method uses a multi-dimensional risk representation that allows a standard OLAP engine to perform analysis on multi-dimensional data corresponding to a portfolio of financial positions. The analysis includes context-dependent, heterogeneous aggregation functions. The multi-dimensional data is represented as a multi-layered multi-dimensional cube (“outer” cube), which consists of dimensions and cells. Each cell includes a set of coordinates and an inner multi-dimensional cube (“inner” cube). Dimensions of the inner cube include all dimensions required for aggregations. Dimensions of the outer cube include only dimensions needed for context (or reporting). An aggregation is performed on the set of measures of the inner cube based on a context for the aggregation provided by the outer cube.
