Terminology

2240 terms, tools, patterns and metrics an architect is expected to use precisely. Each one gets a short explanation of what it is, and — where it matters — what it is commonly confused with. Search filters as you type; the column headers sort.

Term	Kind	Topic	What it is
Tenant-Scoped Layout Key Tenant Clustering Key, Tenant-Aligned Physical Layout	pattern	Data Platform Tenancy	Making the tenant identifier the column that governs a table's physical organisation, so isolation, per-tenant cost attribution and per-tenant deletion come from layout rather than from access control alone.
Transformation Framework ELT Framework, SQL Transformation Tool	tool	Transformation Frameworks	A tool that turns warehouse transformations into version-controlled, tested, dependency-aware code rather than a collection of scheduled scripts.
Wall-Clock Schedule Hazard Local-Time Trigger Hazard, DST Schedule Ambiguity	concept	Batch Orchestration	The class of batch faults caused by triggering work on a civil clock that repeats, skips or shifts, producing duplicate or missing runs that no job reports as an error.
Warehouse Concurrency Scaling	concept	Workload Isolation	Adding compute clusters to absorb concurrent queries rather than queueing them, and the cost behaviour that turns a queue into a bill.
Warehouse Migration	practice	Warehouse Migration	Moving analytics from one platform to another, where the difficulty is almost never the data and almost always the accumulated logic and consumers.
Workflow Schedulers	tool	Workflow Schedulers	Tools that run interdependent tasks in the right order with retries and visibility — where the value is the explicit dependency graph, not the schedule.
Workload Fit Assessment	practice	Warehouse, Lake & Lakehouse	Choosing between warehouse, lake and lakehouse by the workloads that must run, rather than by which one is currently fashionable.
Workload Isolation	practice	Workload Isolation	Preventing one team's expensive query or backfill from degrading everyone else's analytics, by separating compute rather than sharing one pool.
Zombie Task Orphaned Task, Heartbeat-Expired Task	concept	Batch Orchestration	A task whose worker has stopped reporting to the scheduler but whose process may still be running and writing, so the orchestrator retries work that has not actually stopped.
