How are ER diagrams? What tools do you use to draw them?

To create ER diagrams, I use several tools depending on the task and team preferences:

• draw.io (diagrams.net) — a free and user-friendly online tool with support for exporting to various formats.
• dbdiagram.io — a specialized service for quickly creating diagrams based on a simple DSL.
• Microsoft Visio — for more formal and detailed diagrams, especially in a corporate environment.
• ER diagrams in IDEs — for example, in DataGrip or DBeaver, you can automatically generate a diagram based on the database structure.

The choice of tool depends on the requirements for detail, the need for collaboration, and integration with other systems.
