DATAllegro was a company that specialized in datawarehousing applicances. It was founded by Stuart Frost in 2003 inspired by and as a competitor to Data warehouse appliance pioneer Netezza.[1] In contrast to rival Netezza - which used "commodity" PowerPC chips - the DATAllegro architecture was implemented on commodity hardware from OEMs such as Dell Computer Corp., Cisco Systems Inc., and EMC Corp. DATAllegro - like Netezza - used open source software stack (Ingres DBMS running on Linux). Microsoft announced it had acquired DATAllegro as of September 2008.[2] SQL Server Parallel Data Warehouse (PDW) is the successor product to DATAllegro on Windows Server using a version of the SQL Server database engine[3]
