Does this skill support different SQL dialects?

While the core examples focus on PostgreSQL, the fundamental design principles and standard SQL syntax provided are applicable to most relational databases including MySQL, MariaDB, and SQL Server.

Can it help me with database normalization?

Yes, the skill specifically guides the design process through 1NF, 2NF, and 3NF to ensure your data is stored efficiently without redundancy.

Does it provide guidance on when to use indexes?

Yes, it includes strategic indexing rules for foreign keys, join columns, and frequently filtered fields, while also warning against over-indexing on small or frequently updated tables.

How does it handle many-to-many relationships?

It provides standardized patterns for junction tables (bridge tables) including foreign key constraints and composite primary keys to properly model many-to-many associations.

Database Management

Architect robust relational database structures with optimized normalization, indexing, and data integrity constraints.

About

The Schema Designer skill empowers Claude to act as a professional database architect, guiding the creation of efficient and scalable relational database models. It handles everything from initial entity identification to advanced normalization (3NF) and the implementation of complex relationships like many-to-many junction tables. By integrating best practices for indexing, constraints, and common design patterns like soft deletes or audit trails, this skill ensures your database architecture is performant and maintains high data integrity from day one.
