The notion that OLAP/DW data do not require integrity is somewhat of an illusion. DWs must be populated quite often and, given that most OLTP databases that are denormalized do not deploy the necessary constraints, chances are that their integrity is questionable. In absence of integrity enforcement at the DW level, the risk of inconsistent data is considerable (note that the same is true of even historical data, which is also read-only).
