Also @Greg Johnson, Zach is a busy guy I’m sure hehe. So I found a recent response of his that I think answers both our questions.

Skuid cannot currently connect directly to SQL databases - direct SQL connections are on our near-term roadmap.
For Skuid to connect to a SQL database right now, you would need to setup a REST or OData API to serve as a middle layer between Skuid and the database. The easiest way to do this would be to go through an integration vendor such as Progress DataDirect or Mulesoft.
