Explains MDM hub styles
Registry (index to sources), consolidation (persisted read-only golden copy), coexistence (golden copy synchronised back) and centralised or transaction hub (the hub authors) - and what each assumes (DMBOK2 ch. 10).
Can AI do this?
AI does this well Most of the tested AI models master this. 4 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 100% | Mastered |
| gemini-3.5-flash-lite | Low cost | 100% | Mastered |
| gpt-6-luna | Low cost | 100% | Mastered |
| claude-haiku-5-5 | Low cost | 100% | Mastered |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: Registry (index to sources), consolidation (persisted read-only golden copy), coexistence (golden copy synchronised back) and centralised or transaction hub (the hub authors) - and what each assumes (DMBOK2 ch. 10).
