A hybrid dynamic database schema is described. The schema is a hybrid of both horizontal and vertical database schema, in that, while a vertical schema has only one dimension—dimension value pair per table/record, the hybrid schema of the present invention provides for multiple dimension—dimension value pairs per table/record. The schema provides for additional fields, so called “DimSet” fields, with each additional field comprising one and typically multiple dimension—dimension value pairs. Thus, while a vertical database schema can only perform aggregation/segregation using one isolated dimension—dimension pair, the hybrid schema of the present invention is capable of performing multiple aggregations/segregation processes simultaneously (i.e., in parallel) using the multiple dimension fields. The dynamic nature of the database schema is realized by the ability of the schema to support various different additional fields (i.e., additional “DimSet” fields) with different combinations of dimension-dimension value pairs.
