Configurable Joins unlock a new level of flexibility in Slate queries, but only once you understand the foundation. This session starts with query bases: what they are, how record-based, related, and system-based objects differ, and how to build exports and layer filters using AND/OR logic to control your output. From there, it walks through the core decision every query builder faces: when to use a one-to-one join versus one-to-many, using a person and address relationship to show how your data structure determines the right call.
