I agree - it doesn't seem normalised (it seems to repeat a lot of info for
each colour).

Adam...the example was simple and has nothing to do with products ;-)

Typically (using prod/cat/colour example) you'd have 4 tables (product,
category, colour, product_colour) and the products table would be joined to
the category table via cat_id (one to one) and to the colour table via the
product_colour table which contains colour_id and product_id (one to many).

What I've been shown is a central table that has product_id, cat_id,
colour_id and the cat_id would be duplicated for each colour_id.

I've never seen it done this way...seems clumsy
