Term	Kind	Topic	What it is
Derived Store Discipline One Authoritative Store Per Fact, No Dual Authority	concept	Polyglot Persistence	The rule that every fact has exactly one authoritative store and every other copy is explicitly derived, rebuildable and populated by a documented pipeline - the discipline that makes multiple datastores defensible.
Operational vs Analytical Store	concept	Polyglot Persistence	The separation between the store serving the application's transactions and the one serving reporting and analysis, and the mechanism connecting them.
Polyglot Persistence	concept	Polyglot Persistence	Using different storage engines for different workloads within one system — justified by genuine workload divergence, and frequently not.
