Technical Notes

Enterprise Information System (CMS Platform)

Design notes documenting the architecture and trade-offs behind an internal CMS platform built to support research group operations.

Context

The platform was developed to manage institutional content and administrative workflows, replacing fragmented processes with a centralized system.

Core Constraints

  • Role-based access control (RBAC) with clear permission boundaries.
  • Traceable administrative actions through audit logging.
  • Normalized relational schema for long-term maintainability.

Key Design Decisions

Implemented as a layered application with a centralized PostgreSQL database to reduce accidental privilege escalation.

Administrative actions recorded explicitly to support future inspection and debugging.

Trade-offs

Prioritizing relational correctness and explicit workflows increased initial effort but simplified long-term maintenance.

Outcome

Reduced manual administrative work and introduced consistent, auditable content workflows.
