What are Connections?

Steps Covered in This Video

1. A connection field links two tables together — like Customers and Orders — so they can “talk” to each other.
2. Connections work like lookup fields: instead of typing the same value repeatedly, you select it from a dropdown.
3. You only need one connection field, and it always goes in the child table (e.g., Orders connect to Customers).
4. With one connection, you can:
   • Display related records on a page
   • Filter data by who’s logged in
   • Pull values from other tables
   • Perform calculations across tables
   • Automate workflows

👉 None of this is possible without connections in place first.
