Could you say what you want to do with the data? Also, is each row a piece of data? - I *think* what you have shown is a schema rather than the sample data itself, which is rather to prejudge the answer. In my limited experience getting the data structure right at the outset saves a shed load of effort later on, and I'd love to kick in my £/50, but with my low-grade version of SOPW::Psychic I'm not sure what the question is.
