database-schema-designer
Production-ready SQL and NoSQL schemas with normalization, indexing, and migration strategies built in.
- Generates complete schemas from natural language descriptions, covering entities, relationships, constraints, and indexes tailored to SQL or NoSQL databases
- Provides normalization guidance (1NF through 3NF), foreign key strategies with ON DELETE rules, and composite index planning based on access patterns
- Includes anti-patterns reference (FLOAT for money, missing FK indexes, non-reversible migrations) and verification checklist for schema quality
- Supports zero-downtime migration patterns, denormalization for read-heavy workloads, and performance optimization via EXPLAIN analysis and query pattern matching
Database Schema Designer
Design production-ready database schemas with best practices built-in.
Quick Start
Just describe your data model:
design a schema for an e-commerce platform with users, products, orders
You'll get a complete SQL schema like:
CREATE TABLE users (
id BIGINT AUTO_INCREMENT PRIMARY KEY,

mermaid-diagrams
Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes, algorithms, user journeys), entity relationship diagrams (database schemas), C4 architecture diagrams (system context, containers, components), state diagrams, git graphs, pie charts, gantt charts, or any other diagram type. Triggers include requests to "diagram", "visualize", "model", "map out", "show the flow", or when explaining system architecture, database design, code structure, or user/application flows.
