Abstract: A system, computer-implemented method, and computer program product for performing integrated transactional and data warehouse business intelligence analysis using a correlated report constructed from data correlations between current transactional data and historical data from a data warehouse. The method commences by retrieving a transactional data record from an online transactional processing (OLTP) system, the transactional data record comprising at least one OLTP business intelligence value of a particular business intelligence attribute, then receiving from a storage system, results of a query to a data warehouse, the results comprising a historical business intelligence value of the same business intelligence attribute. Modules within the system (e.g., a business intelligence application) perform processing to combine the OLTP business intelligence value with the historical business intelligence value to form a correlated report and transmit the correlated report for displaying on a single surface.
