I am not sure if the following scheme might be useful to achieve the requirements in the described scenario?:

Create an actual or effective Materialized Query Table (MQT) that is a summary of the historical data using desired aggregates. Use that somewhat static data as reference-data for effecting the sanity-check of the attributes of the new data\order. Schedule a refresh of the summary-data after some period of time or number of additions [or changes] to the [apparently historical] detail-data, or after some deviation that is deemed acceptable to be applied to the detail-data.
