Governed architecture portfolio

Use one private copy. Submit no personal/student information to the public repository. Use the section identifiers below to connect your portfolio to the phase instructions.

Section	Required content
Phase_1_Requirements	Stakeholder statement, entities, relationships, attributes, confidence, follow-up question
Phase_2_LDM	Editable ERD, keys, attributes, cardinality, junctions; annotate logical relationships, delete/update behavior, proposed enforcement and verification in the existing rationale
Phase_3_OLTP_vs_OLAP	Grain, facts/dimensions, workload placement and tradeoff memo
Phase_4_Governance	Owner, handling classification (Public / Internal / Sensitive / Restricted), confidentiality impact (Low / Medium / High), regulatory applicability/uncertainty, retention, risk, permitted use, proposed control and evidence status
Phase_5_Evaluation	Claim, observed evidence, limitations, missing deployment validation
Phase_6_Evidence	Evidence appendix used by capstone Phase 5 (not the presentation phase)
Architecture defense	Presentation and responses to stakeholder questions (capstone Phase 6)
Individual reflection	Contribution, learning, uncertainty and next improvement (capstone Phase 7)
Governance operations	Observation, policy, accountable role, review decision, action, verification and next review trigger
AI governance	Dataset card, bias/mitigation analysis, transparency, accountability and deploy/reject decision

These are fields in your existing phase entries, not additional reports. Stakeholder assertions, proposed controls and demonstrated behavior must remain distinguishable.

For each claim label it demonstrated, simulated, proposed, or untested. Demonstrated means implemented and tested in the named environment; untested means implemented or asserted without sufficient verification. Include environment, command or artifact, result and limitation. Attach the peer review and response. Do not use generic lab screenshots as proof of unimplemented capstone controls.

Claim and revision record

Copy these fields for each important claim. Use requirement identifiers of your own choosing so the same decision can be traced across phases.

Requirement/source	Decision and alternative	Evidence label	Artifact/command and environment	Result and limitation	Next check / accountable role
Fill in	Fill in	Demonstrated / simulated / proposed / untested	Fill in	Fill in	Fill in

For each revision record the phase, feedback or new evidence, change, rationale and affected artifacts. Keep team contributions and reviewer identities private.
