There’s a few posts regarding this floating around, but here is one with a few follow-up posts.

I wouldn’t say that I have a strict naming convention, but I like to prefix computed columns with their type.
As for column grouping, I’ve seen a couple of different ways that people group their columns with the ‘/’ character. Some will group by column type (all booleans, all relations, all IF columns, etc.). I personally tend to group by function. A lot of times I’ll have several columns that work together to perform a function or or columns that are related to each other, so I’ll end up grouping them together that way. That way it’s easier to collapse a group of columns that are related to each other or part of one function. Also, it’s much easier to find the column you need in the app…much like folder/file system. I explain a little more here.
