Abstract: A data aggregations application is disclosed that can create data aggregations from transaction data reported by an upstream system. Data aggregations that are interrelated to one another are generated. The transaction data can be stored only in leaf nodes with transaction idempotency maintained. Parent nodes can be dependent upon the leaf nodes so that transaction is not required to be stored in the parent nodes.
