Description The Database Schema Designer translates your application requirements into production-ready database schemas. Describe your data models and relationships, choose your database engine, and get complete DDL scripts with tables, columns, data types, primary/foreign keys, indexes, constraints, and migration files. Supports relational (PostgreSQL, MySQL, SQLite), document (MongoDB, DynamoDB), and key-value (Redis) databases with normalized, denormalized, and star schema designs. The Technical Specification Generator produces comprehensive technical documents that engineering teams actually read and follow. Whether you need an RFC for a new architecture, a design doc for a feature, an ADR for a technology choice, or a technical brief for stakeholders — get a well-structured document with problem statement, proposed solution, alternatives analysis, implementation plan, risks, and success metrics.

Use Cases
  • Design a relational schema for a SaaS application with multi-tenancy support
  • Create MongoDB collection schemas with embedded documents and indexes
  • Build a star schema for a data warehouse or analytics pipeline
  • Generate migration scripts for an incremental database evolution
  • Design a DynamoDB single-table design with GSI access patterns
  • Write an RFC for a major architectural change (microservices migration, new database, API redesign)
  • Create a design document for a new feature with data model, API contracts, and rollout plan
  • Record Architecture Decision Records (ADRs) for technology choices your team makes
  • Produce a technical brief for stakeholders explaining a system's capabilities and limitations
  • Draft a PRD that bridges product requirements with technical implementation details
Pro Tips
  • Describe your read and write patterns in the requirements — this helps the generator choose between normalized and denormalized designs.
  • For PostgreSQL, the generator will use advanced features like JSONB columns, partial indexes, and generated columns where appropriate.
  • Request 'Migration Script' output format if you use tools like Flyway, Liquibase, Alembic, or Knex — the output includes versioned migration files.
  • Include constraints in your description — budget, timeline, team size, existing tech stack — so the spec accounts for real-world limitations.
  • For the 'Alternatives Considered' section to be useful, mention any approaches you have already thought about and why you are leaning toward your proposed solution.
  • Request 'Implementation-ready' detail level when you want the spec to serve as an engineering task breakdown — it will include specific API endpoints, database queries, and code structure.
