The data comes in and it is usually dirty. It requires cleaning before it is accepted into the data warehouse. All day long people send this data. They typically think it is just pushed into the warehouse and put on its appropriate shelf. Little do they know how much work goes into it!
The warehouse is virtual, yet it is also real. The work is virtual--yet the data is real.
Out of all the many jobs I've ever had, this is definitely one of them.
