A friend of mine was interviewing for a data warehouse and Business Object role But he was asked about the Manhattan database?
I have Googled "Manhattan database" and even searched for it on Bing and Yahoo but have found no relevant information.
Any help would be greatly appreciated!
The closest thing may be Microsoft project Madison, which is an auto-scalable data-warehouse appliance. The interviewer may have mixed-up Manhattan with Madison (Square Garden) which happens to be located in Manhattan.
Or, maybe he/she did it on purpose to see how good was your friend at data cleaning and conforming. :)
