My own view is they should either be all plural or all singular. Just pick one. But I do gravitate to singular because all nouns have naturally consistent singular words. The same cannot be said of plural. e.g. Moose, Cactus, and any other word that ends in an 's'.

I used to do all plural but then I read a good argument online for doing singular so I switched to that for the next project and I've done singular ever since.

The few advantages of singular:

1. It's not always clear what the plural of something should be.

2. Chances are the singular maps better to your application layer (Person class <=> Person table).
