A system is described that includes a data warehouse and a platform independent data warehouse load application operable to run on the system. The load application includes a sequencing unit configured to utilize timestamp data from incoming data to be stored in the data warehouse and a relational algebra of set operators to identify and sequence net changes between the incoming data and data previously stored within the data warehouse. The load application is configured to non-intrusively load the identified and sequenced net changes into the data warehouse.
