To model your databases, DrawDB is likely the tool you need! This robust entity-relationship diagram editor (DBER) works directly in your browser, allowing you to build diagrams in just a few clicks, export SQL scripts, customize your editor, and much more—all without the need to create an account.
With this site, you can add tables, define relationships, specify attributes, and much more in a visual and intuitive way. Tables can be created with the necessary fields and indexes, and relationships are easily established by dragging and dropping elements. One of the great advantages of DrawDB is that it requires no installation. Everything happens in your web browser, allowing you to access it from anywhere. This is convenient for teams needing to collaborate remotely on database design.
The tool automatically generates SQL scripts corresponding to your diagrams, in various dialects such as MySQL, PostgreSQL, SQLite, MariaDB, or SQL Server. Everything can be exported in SQL, JSON, or image format to be used elsewhere. DrawDB remains customizable, allowing you to adjust colors, fonts, styles, and many other settings to tailor the editor to your preferences. You thus have full control over the appearance of your diagrams.
In addition to import/export capabilities and customization, it offers many practical features like keyboard shortcuts to speed up development, predefined or custom templates to save time, a presentation mode for team meetings, task tracking, and even error detection in diagrams to ensure that the generated scripts are correct. It supports both relational and object-relational databases, allowing you to add custom types.
It’s a great open-source and free project to explore on DrawDB. However, keep in mind that diagrams are saved in your browser, so be sure to save your data before clearing the cache or history.
