Data Modeling

This handles the full spectrum of database design work, from sketching conceptual ERDs with business stakeholders to generating physical schemas with indexes and constraints. It covers all three modeling levels, supports multiple notation styles like Crow's Foot and Chen, and walks you through the complete workflow: entity identification, attribute definition, relationship mapping, normalization, and physical implementation. The normalization guidance is solid, including when to deliberately denormalize for performance. Outputs Mermaid diagrams and data dictionaries. If you're designing a new system's data layer or documenting an existing one, this gives you the structure and vocabulary to do it right.
