kickstart Posted September 8, 2009 Share Posted September 8, 2009 Hi Logically the books are purchased by people. Have a table of people and a table of books, and a table list when people buy particular books. This way there should be no duplicated data, hence effectively first normal form. All the best Keith Quote Link to comment Share on other sites More sharing options...
