Compression Teach-Back & Repair
5-minute teach-back
Teach Chapter 8’s lifecycle, architecture patterns and governance without notes. Your explanation should connect:
need → evidence → architecture → mappings/orchestration → services/flows/migration/publication/CEP → monitoring → Metadata/lineage/governance → metrics.
2-minute teach-back
Explain the eight high-confusion families:
- ETL / ELT
- CDC / Replication
- Async / Sync
- Point-to-point / Hub
- Mapping / Orchestration
- Discovery / Profiling
- EAI / ESB / SOA / CEP
- Federation / Virtualization
For each, state the deciding clue, not just two definitions.
30-second teach-back
DII gets data where it is needed, when needed, in the right form. Plan with requirements, discovery, profiling, lineage and rules; design reusable interaction patterns, models, mappings and orchestration; build services, flows, migration, publication and event processing; then operate to consumer service needs while maintaining Metadata/lineage and governing business meaning and sharing obligations.
Self-score
- Green: correct and explainable without cues.
- Yellow: correct but slow or unable to state the deciding clue.
- Red: wrong, reversed, confused or dependent on recognition.
Only Yellow/Red patterns should feed Artifact 08 later.
Repair loop
- Pick the five slowest/least-confident prompts.
- Write each nearest confusion pair.
- State one deciding clue.
- Invent a changed-fact scenario that makes the paired concept correct.
- Re-answer later without notes; only repeated weakness becomes an Artifact 08 item.
Final readiness test
You are not done merely because you recognize ETL, ESB or CDC. You should be able to say why a changed business requirement changes the architecture answer.
