Database normalization for CSV files. Analyzes data structure, detects functional dependencies, and decomposes into normalized tables (1NF-BCNF). Outputs multiple CSV files, SQL DDL, and Mermaid ERD. Use when: (1) converting flat CSV data into relational database schema, (2) reducing data redundancy, (3) preparing denormalized exports for database import, (4) user mentions "normalize", "1NF/2NF/3NF/BCNF", "functional dependencies", or "database design".
