On the File menu, point to New.-> Click Software, and then double click the icon of UML Model Diagram. As a downside, the app is not what you would call user-friendly or intuitive (on the OS X platform at least), and this automatically translates into a steeper learning curve until one can be comfortable working with it.Open a blank drawing page and the libraries including shapes needed for creating UML Diagrams. Taking all things into consideration, TerraER is a simple open source application that works well as a learning tool for students that have to study data modeling. With the help of the contextual menus, you can also copy, cut, rename, duplicate any element with ease.Īnother thing you should know is the fact that TerraER enables you to export your projects, regardless of their size, as XML files. Cross-platform modeling tool designed to help you build ER modelsĭespite its appalling user-interface, working with this application is not easy, but not very hard either, as it enables you to drag and drop, move, rename, resize, and rearrange almost every element. The Drawing toolbar provides you with quick access towards a selection tool, and also enables you to add entities, weak entities, relationship, entity relationship, roles, attributes, attribute connection, key attributes, derived attributes, and multi-value attributes, optional connections, disjunctions, overlapping and generalization connections, just to name a few.

Therefore, it wouldn’t be misguided to say that TerraER was created to help students or other type of users to learn the basic concepts of data modeling, especially in a field like software engineering. TerraER is a straightforward and Java based modeling application that was designed from the ground up to help you build ER (entity-relationships) models.
