Term	Kind	Topic	What it is
Computation-Only Collaboration	pattern	Data Sharing & Clean Rooms	Two parties analysing their combined data without either receiving the other's records, by permitting only queries whose outputs are aggregate.
Metric Definition Layer	pattern	Semantic Layer	Business metrics defined once in a versioned, tested place and served to every consuming tool, so the number cannot differ by which tool asked.
Predicate-Based Filtering	pattern	Row & Column-Level Security	A policy that appends a filter to every query on a table based on who is asking, so one physical table serves many audiences safely.
Purpose-Based Access	pattern	Data Access Models	Granting access for a stated and recorded purpose rather than by role alone, which is what several data protection regimes actually require.
