Entity-Relation Mapping Editor

A simple UI for editing entity-relation mapping diagrams.

Usage

This program is distributed as an executable jar file. You can find the latest release here. You will need Java installed on your computer (version 8 or higher). You can install an OpenJDK version of Java here.

Simply double-click on the jar file, or execute java -jar <jar file> from the command line (where <jar file> is replaced with the path to your actual jar file).

The above image shows the application's user-interface.

Instructions

The interface and menus should be pretty self-explanatory, but here are some tips to get you started:

• Click on a relation to select it.
• You can CTRL + click to select multiple relations.
• Drag the relations to move them around in the window.
• Right-click on different areas to access context menus with some helpful actions.
• When exporting the model to an image, be sure to add the desired image file extension (.png, .jpg, .bmp, etc.), or the application will default to .png.
