DATAllegro was a company that specializes in datawarehousing applicances. It was founded by Stuart Frost in 2003 inspired by and as a competitor to Data warehouse appliance pioneer Netezza. In contrast to rival Netezza - which still uses "commodity" PowerPC chips - DATAllegro architecture is implemented on all-commodity hardware from OEMs such as Dell Computer Corp., Cisco Systems Inc., and EMC Corp. DATAllegro - like Netezza - uses open source software stack (Ingres DBMS running on Linux). Microsoft announced it had acquired DATAllegro as of September 2008.
