Terminology

991 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
Analytical Estate Topology	concept	Data Platform Architecture	The full picture of where analytical data lands, is transformed and is served, including the paths that bypass the intended one.
Attribute History Strategy	concept	Slowly Changing Dimensions	The per-attribute decision about whether history is overwritten, versioned or kept alongside the current value, which is a business question rather than a technical one.
Bronze Layer Contract	concept	Medallion Architecture	What the raw landing zone promises and refuses to promise — a faithful replayable copy of the source, with no correction applied.
Compute Isolation Boundary	concept	Data Platform Tenancy	The line across which one domain's analytical workload cannot affect another's performance, cost attribution or access.
DAG Dependency	concept	Batch Orchestration	The declared edge stating that one task must not start until another has succeeded, and the difference between that and merely running later.
Partition Pruning	concept	Storage Layout & Partitioning	The query planner skipping files whose partition values cannot satisfy the predicate, which is the single largest determinant of analytical query cost.
Scheduler Control Plane	concept	Workflow Schedulers	The orchestrator's own state and availability, which becomes a critical dependency for every pipeline it runs.
Small File Problem	concept	File Formats & Compaction	The degradation that follows from many tiny files — metadata operations dominating, compression failing, and columnar formats losing their advantage.
SQL Transformation Model	concept	Transformation Frameworks	A named, versioned, tested SELECT statement that declares its own dependencies, turning transformation logic into reviewable software.
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.
