Zusammenfassung:	A system, method and program product for providing latency management for use with a database management system. A system is disclosed having: a system for capturing and storing a maximum latency (ML) whenever a derived source is created from a source data; a system for determining a difference between a last refresh timestamp of the source data and the last refresh timestamp of the derived source in response to a query; and a system for causing the source data to be used in response to the difference being greater than the ML, and for causing the derived source to be used in response to the difference being less than the ML.
