I'm looking for a software that will let me draw Entity-relationship models.

Something similar to Microsoft Visio would be nice. What software would you recommend?


Dia (Click to install)

Dia is roughly inspired by the commercial Windows program 'Visio,' though more geared towards informal diagrams for casual use. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

You can also use Pencil

The Pencil Project's unique mission is to build a free and opensource tool for making diagrams and GUI prototyping that everyone can use.

The Drawing component of Open / Libre Office should also allow you to do what you wish.
