Answer / sanchari chowdhury
Records in a OLTP database can be updated or modified or
deleted. However,the same is not possible in DW.
OLTP database is used for transactional purposes e.g. day-
to-day sales or finance and DW is used for analytical
decisions.DW is mainly used for business decisions to
ensure stability of the organisation by curbing the
possible failures. This is possible because it contains the
historical or the archived data for analysis.
