Your tables suggest you may need to do some more work on RDBM design. You have features and attributes of Products spread throughout several tables, when I believe they could all be in one table, with the appropriate fields. You want to try and collect all information about a thing or event in one table. In your case, so far I've only seen mention of 'Products'. What else are you going to put in your database, if anything?

Try and get a good book on relational database design. Some good ones that I use are 'Database Design for Mere Mortals' by Michael Hernandez, 'SQL Queries for Mere Mortals' by same author, and 'MySQL' by Paul Dubois.
