This is completely wrong
No, it's completely right: the traditional way to use a database is to blob everything together in to one huge table, preferably with many NULLs, then limit your query to SELECT * FROM Table; and finally process the results directly in VB6, with bonus points for a buggy parser for unpicking comma separated fields.
Note: he said "traditional" not "sane relational".
Sarcasm aside, his reason for not using a relational database is that he'd need to use more than one table and then he'd have to perform joins on them, which sounds very much like saying the reason not to use SQL is because the problem fits exactly into what SQL is designed to do.
But hey, his new solution is in the cloud so it must be better.
