Use this skill when creating or modifying ORM model files, database entity definitions, or data structure schemas. When defining table relationships, foreign keys, and cascade behaviors. When implementing model validation rules, timestamps, or indexes. When working with model files in frameworks like SQLAlchemy, Sequelize, ActiveRecord, SQLx, Prisma, or similar ORMs. When choosing appropriate data types for columns or establishing data integrity constraints (NOT NULL, UNIQUE, foreign keys).

• When choosing appropriate data types for database columns
• When adding timestamps (created_at, updated_at) to models
• When implementing data integrity constraints (NOT NULL, UNIQUE, CHECK)
• When creating indexes on frequently queried columns
• When working with model validation at the ORM layer
