Database Tools

Database queries, schemas, and utilities

Database queries, schemas, and conversions

Database tools handle the schema-and-query layer that lives between your ORM and your DBA: SQL ↔ Prisma schema converters, ER-diagram generators from a SQL DDL paste, query formatters that handle CTEs and window functions without choking, dummy-data generators for fixture creation, MongoDB query → SQL translators for when you're migrating between stores. Useful during data-modeling phases, when you're onboarding to an unfamiliar codebase's schema, or when you need to communicate a schema visually to a non-technical stakeholder. None of the tools require a database connection — everything works on pasted-in DDL and JSON.
