You'll find a ton of opinion on this if you look online.. The general
consensus AFAICT is to not have plural table names, despite its
initial seductive appeal (select * from authors, has a ring to it).
Apart from weirdnesses like person/people, the single row as you say
expressed as a plural sounds odd, as do plurals in join conditions.

There's an argument from the ER crowd that entities (classes) are
singular so why transform your singular entity names to plural when
making concrete in SQL/database?

My personal experience has been initially plural and then after much
SQL/DB work going back to singular as I hated all the little awkward
moments that seem to crop up.

(There's the argument that RoR requires plural table names so that
must be wrong :-))

Great talk btw :)
