TerraER: A robust application that lets you easily create comprehensive diagrams and ER models, for project management or database usage education

TerraER is feature-rich piece of software that lets you easily create data models in a friendly graphic environment.

The program lets you adjust the relations and intermediate elements, as well as the number and location of entities. You simply need to place them in the dedicated form then save and optionally print the project.

TerraER can be used to create diagrams of entities and relations, each element being customizable so it’s possible to rename, move and resize it. You can view a tree structure of all the added elements in the left column.

You can also use various building tools, hide/show the background grid, as well as move any selected element pixel by pixel. Moreover, you can select multiple items and align them, duplicate items, and save the project for further editing, print it or export it as an XML document.
