Terminology

2225 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
Classification Propagation Label Inheritance, Lineage-Aware Classification, Derived Sensitivity	practice	Sensitivity Labelling	Carrying a column's sensitivity classification through every derived table, view and export, so that copying restricted data into an aggregate does not silently strip its protection.
Classification Propagation Labels Travelling Through Lineage, Derived-Data Sensitivity	practice	Sensitivity Labelling	Carrying a sensitivity label through every derivation, so a restricted column copied into an aggregate, a training set or an export remains subject to its controls.
Label Inheritance Classification Propagation, Sensitivity Inheritance	practice	Sensitivity Labelling	Automatically assigning a derived dataset the highest sensitivity of its inputs, so that aggregates and transformations do not silently escape the controls that applied to their sources.
Over-Classification Label Inflation, Maximum Propagation Collapse	concept	Sensitivity Labelling	The state in which so much of an estate carries the highest sensitivity label that its controls become unworkable, and people route around them - producing less protection than a coarser scheme would.
Sensitivity Labelling Data Classification Tagging	practice	Sensitivity Labelling	Attaching a machine-readable classification to data at the column or asset level, so that downstream controls can be applied automatically.
Sensitivity Propagation	concept	Sensitivity Labelling	The rule that a derived dataset inherits the highest sensitivity of its inputs unless a named transformation demonstrably lowers it.
