<p>The invention discloses a method for aggregating data with a deliverer. The method comprises: selecting a stage table bucket from a stage table, the bucket comprising source data and being identified by a bucket identifier; reading a subset of the source data contained in the bucket, the subset being determined by predetermined subset definition data; aggregating, based on the subset definition data, the read subset of the source data; inserting the aggregated information into an aggregate table bucket in an aggregate table, the aggregate table bucket having the bucket identifier; and updating bucket deliverer metadata.</p> |
