My guess is they want to get in and pull the information and create some type of custom view. Maybe there is information in the canned report they don't want, or if they can pull the information into a spreadsheet they can manipulate it. No telling. In the Data Dictionary you can pull your information. I do not know specifically wnat the database name is when doing this, but I have pulled information like this before. Personally I feel uncomfortable letting people do this because I have seen manipulated data in reports and sooner ro later they will come to you and ask you "Why is it like this?" Avaya Prof Services can do this, but it's pricy.
Maybe someone is learning Crystal Reports and justs wants to tool around, but pulling data from the system like this is a resource and memory hog. if they do this during peak times, walk up slowly behind them and give them a good NCIS smack on the head and walk away. You should only extract information this way during off-peak hours.
Hope this helps.
