Stage 4: Build the conceptual model and taxonomies
Knobit of Data modelling · K-420 · Skill
Recognises a structural error in a taxonomy hierarchy
What it means
The hierarchy contains a cycle, a node that is not a concept in the model, or no declared root. Validator: `CON-008`, `CON-009`, `CON-010`, `CON-016`.
How it is assessed
Flags the deficient case and passes the acceptable one. Deficient: Current account → Payment account → Current account; `children: [CC-099]` where CC-099 does not exist Acceptable: Decide which is broader, or merge them if they are synonyms; add CC-099 to `concepts` before referencing it
