That said, you can approximate an IS-A relationship between tables, but it's cumbersome and prone to mistakes. This statement seems contradictory to your idea about a separate table for optional attributes. That is merely a further generalization of the approximate IS-A relationship, and is equally cumbersome and prone to mistakes, if not moreso. How is it more cumbersome to have the tables
Than to have the tables you are proposing?
