Bringing Requirement Modeling into Metadata-Driven Data Architecture
From UML and PowerDesigner roots to YAML-based modeling in VSCode
Introduction — The Missing Bridge Between Business Intent and Data Design
Modern data architecture has evolved rapidly. We’ve moved from hand-crafted SQL to metadata-driven frameworks, where YAML files and declarative logic generate the data platform itself.
We’ve learned to describe conceptual, logical, and physical models as metadata-as-code, feeding automated engines that generate tables, pipelines, and tests.
But one crucial layer is often missing: Requirements.
🔹Where do business requirements live?
🔹How are they linked to conceptual entities and logical models?
🔹And how can we trace them — from stakeholder intent to physical implementation?
This is the bridge we’ll rebuild. Requirement modeling was once native to tools like PowerDesigner and UML; now it deserves a modern home in YAML, Git, and VSCode.
