Declarative-architecture

Analytical systems are built for questions that do not exist yet. A layered DAS/DAB/DAR architecture with ensemble modeling makes continuous change survivable.

Skills, semantic layers, and ontologies make analytics agents work, until they hit the messy data underneath. The durable fix is structural, not more context.

Why we built Daana CLI to reclaim lost data modeling knowledge and make proven architectural patterns accessible through modern declarative tooling.

Replace hand-written staging SQL with declarative YAML contracts. A generator reads contracts and produces consistent, type-safe SQL across all your source systems. The contract becomes the documentation, the schema definition, and the transformation logic - all in one artifact.

Data engineering is shifting from writing code to declaring intent. The rise of model-driven data engineers who design semantic models rather than implement pipelines, and what this means for the future of the discipline.
