Non-Anonymous Surveys

I need to create a survey but I have to know who took the survey and exactly what their answers are?  Everytime I do a survey it makes it anonymous and I can't tell who answered.  Obviously for most surveys you want them anonymous but is there just a way to use the survey and see how the people answered.  I.E. what office supplies do you need.  Do you need a new computer, do you need a new chair.  If they say they need a new chair I need to know who needs a new chair etc.

Thanks!!
