Module 3 Assignment: Storage, indexing, and retrieval

Scenario

You are advising a platform team designing data infrastructure for repeatable model training and monitoring. The stakeholders are: data engineer, ML engineer, security architect, data steward, and platform owner.

Task

Answer the module question: How do access patterns shape storage choices?

Use the module lab and course readings to produce: AI data platform design review with lineage, quality checks, cost controls, and access model focused on storage, indexing, and retrieval: Compare tabular, document, and vector storage options..

Required Evidence

• Define the decision or system boundary in one paragraph.

• Identify the dataset, proxy data, or evidence source you used: synthetic pipeline events with freshness, schema drift, lineage completeness, volume, and access-risk indicators.

• Compare at least two alternatives, baselines, policies, or designs.

• Report one quantitative result or structured scoring table.

• Explain two failure modes and one mitigation for each.

• State what additional evidence would be required before real deployment.

Submission

Submit the completed notebook plus a 900-1200 word memo. The memo must include clear headings for context, method, evidence, risks, recommendation, and open questions.

Acceptance Criteria

Your submission is complete only if another reviewer can reproduce your reasoning from the evidence you provide. You do not need production-grade data, but you must be explicit about proxy-data limits and what would change with real institutional data.
