Let's remove the specific names of which databases we support. Just thinking this is the sort of thing that gets stale (we launch a new data connector!) and we then have to remember to update it here.

how about the change to (e.g. Postgres, MySQL, Snowflake, etc.). i still want there to be familiar names that people recognize to make it more concrete that we support real databases

Sounds good!

The a.name < b.name means a does not equal, right? Any reason to use instead of != ?

you need it to eliminate the symmetrical opposite that the join creates: a, b b, a, a, a, b, b

I think we should try some navigation components vs. adding the Part 1 in the title. We're working on that now in the prod ed style guide.
