What is Erplain?
erplain is an open-source, visual entity relationship diagramming tool for database modeling. It provides an intuitive graphical user interface that allows users to visually map out the entities, attributes, relationships, and cardinality constraints for a database model.
Key features of erplain include:
- Intuitive drag-and-drop interface for adding entities, attributes, and relationships
- Options for customizing entities, attributes, and relationships
- Ability to define cardinality between entities (one-to-one, one-to-many, many-to-many)
- Support for exporting ERD diagrams as image files or SQL code
- Open-source under the MIT license, available for Windows, Mac, and Linux
Unlike paid tools like Lucidchart or SQLDBM, erplain is free to use. It allows developers, database administrators, and others to visually diagram databases for documentation or development purposes. The exported SQL code allows users to easily recreate their database models in applications like MySQL, PostgreSQL, or Oracle.
Overall, erplain combines an easy-to-use interface with powerful ERD diagramming features for free. It's a great open-source alternative for creating, visualizing, and sharing database models.
