Plain language
A popular database built to store information as a web of connected items rather than as tables.
As stated in the literature
A graph database queried with the Cypher language; representative of the structured knowledge-graph stores AI coding agents consult and that are vulnerable to Oracle Poisoning.
Why it matters: It represents the connected knowledge stores that coding agents consult, which can be exploited if their contents are poisoned.
For example, it stores a social network as people connected by 'friend' links, so you can ask who a person's friends-of-friends are.
