Abstract: A computer-implemented method for generating a report from a report definition specifying a plurality of data scopes for a dataset includes interpreting, with a processor, a report definition for the report, the report definition comprising a calculation expression for populating a unit of the report, the calculation expression comprising a data aggregation operation, the data aggregation operation comprising an originating reference to a further data scope, accessing a memory coupled to the processor to obtain data from the dataset for respective subsets of the dataset corresponding with the further data scope, determining, with the processor, an output value for the calculation expression in accordance with the obtained data and the data aggregation operation, and rendering the report based on the output value.

Abstract: Architecture which provides that certain data-bound objects in the report can be configured by the report author to use data from a specific query result rather than take data from the containing data bound object. The report author defines a relationship between the data in the contained object and the data in the container, allowing instances of the descendant object to be correlated with instances of the ancestor object. This relationship can be either explicit with join conditions or implicit due to an intrinsic hierarchical relationship between the query results.
