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.

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).
