Term	Kind	Topic	What it is
Bloom Filter	tool	Data Architecture	A compact probabilistic structure that answers "is this key definitely absent, or possibly present?" — no false negatives, tunable false positives.
Data Catalog	tool	Data Governance	A searchable inventory of datasets with their schema, owner, meaning, freshness, quality and classification.
Document Store	tool	NoSQL Stores	A store that keeps semi-structured documents — typically JSON — retrievable by key and queryable by their contents.
Event Store	tool	Event Sourcing	An append-only store of domain events organised into per-entity streams, serving as the system of record rather than as a log beside it.
Graph Database	tool	NoSQL Stores	A store whose first-class citizens are nodes and the relationships between them, making multi-hop traversal cheap.
Wide-Column Store	tool	NoSQL Stores	A store organised as partitions of sorted rows, designed for very high write throughput and predictable single-partition reads at large scale.
