An RDBMS database is for constant reads/writes and generally contains a smaller amount of data than a warehouse. A data warehouse is for storing a vast amount of historical data that is mostly just hit with reads. In general a data warehouse is optimized for specific types of queries so the query time is kept within reasonable bounds.
