drawDB is a free, open-source, client-side web application for designing relational database schemas and generating SQL. It provides an interactive ER diagram editor with support for multiple database dialects (MySQL, PostgreSQL, SQLite, MariaDB, MSSQL, Oracle), import/export in SQL, DBML, JSON, Mermaid, and Markdown, and features like auto-arrange, auto-connect foreign keys, schema validation, migration generation, and versioning via GitHub Gists. The architecture is a React single-page application (Vite + Tailwind CSS + Semi UI) with state managed through custom React Contexts and hooks, persistence via IndexedDB (Dexie), and an optional cloud backend through an extension system. It is primarily an application, with no data research or ML components.
CloudDM is a database management platform providing unified access to multiple database systems. It features a web-based console interface built with Vue.js and a Java/Spring Boot backend with a plugin architecture for database drivers. The platform combines database querying, management, access control, SQL auditing, CI/CD capabilities, and workflow automation in a single system. The architecture follows a modular, layered design with clear separation between frontend, backend API, service layer, data access layer, and plugin system. Key features include multi-database support (MySQL, PostgreSQL, Oracle, SQL Server, MongoDB, Redis, etc.), SQL parsing and analysis, security rule engine, and extensibility through plugins.
