Database Architecture & Compliance
Case StudyHealthcare Data Platform & HIPAA Compliance
A complete DBMS solution for a research hospital — unifying fragmented clinical and research data into a single, HIPAA-aligned platform with role-based access, PHI encryption, and full auditability.

The Challenge
Where things stood
A mid-size research hospital running both clinical operations and controlled drug studies was held back by fragmented, siloed legacy systems: no encryption at rest, password-only authentication, no centralized audit logging, and no way to support clinical-trial data requirements. The gaps threatened patient safety, research integrity, and regulatory compliance.
Fragmented, siloed patient and research data causing redundant entry and error risk.
No encryption at rest and weak, password-only authentication.
No centralized audit logging — a direct HIPAA compliance failure.
No structured support for clinical-trial data or interoperability with labs and insurers.
The Approach
From analysis to a delivered solution
Designed the data model end to end
Delivered a full conceptual, logical, and physical database design unifying the electronic health record with the research and clinical-trial schema.
Engineered access around least privilege
Role-based access control scoped each department to only the data it needs, with full audit trails for every touch of protected health information.
Built compliance into the architecture
AES-256 encryption at rest, encrypted transport, and centralized audit logging aligned the platform with HIPAA from the schema up rather than bolting it on.
Planned for scale and governance
Recommended the DBMS product and hardware/software architecture, plus a law, ethics, and security management plan for growing patient and study volume.
The Outcome
What it delivered
Unified EHR + research platform
Aligned controls & auditability
Least-privilege access to PHI
Encryption at rest & in transit
Full conceptual-to-physical schema with an enterprise data model.
Role-based access control and complete audit trails.
Clinical-trial workflow support and lab/insurer interoperability.
Law, ethics, and database-security management plan.
Stack & Standards
Anonymized engagement deliverable. Organization details generalized; design and analysis are my own work.
