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
Deterministic Tokenisation	practice	Tokenisation & Masking	Replacing a sensitive value with a stable surrogate so the same input always yields the same token, preserving joins while removing the value.
Dynamic Data Masking Query-Time Masking, Policy-Applied Redaction	pattern	Tokenisation & Masking	Redacting a column's value as the query returns it, based on who is asking - so one physical table serves cleared and uncleared audiences, while every object derived from it escapes the rule.
Token Domain Entropy Tokenised Value Space, Surrogate Input Entropy	concept	Tokenisation & Masking	The size and guessability of the value space a deterministic token is computed from, which decides whether that token is a usable pseudonym or a lookup key an attacker can rebuild without ever touching the vault.
Tokenisation	pattern	Tokenisation & Masking	Replacing a sensitive value with a meaningless surrogate, where the mapping back is held in a separate, tightly controlled vault.
