DB Maker Online

DB Maker Online provides a domain-focused approach to database design, enabling teams to model tables, fields, keys, and relationships without a live database. It generates SQL for PostgreSQL, MySQL, or SQLite, exports JSON Schema for API design, and produces ERD structures for diagrams. Conceptually, the tool treats a database as a set of interrelated entities; users input definitions, and the system validates normalization and referential integrity while offering actionable export artifacts. Users benefit from a consolidated view of schema decisions, change history, and deployment-ready artifacts that align with engineering workflows. Unique value lies in multi-dialect SQL generation, reverse-engineering capabilities, versioned schema snapshots, and streamlined export formats for documentation and automation. Core features include table and field definitions, constraint options, foreign key relationships, and dialect-aware type mapping, complemented by ERD data and migration outlines. Use cases span new schema design, schema evolution planning, and documentation generation for audits and onboarding.
