Vertabelo is an online tool for visual data modeling. It allows you to create physical and conceptual data models using a simple yet powerful drag&drop approach. You can create data models, work on them together with your team and generate SQL DDL scripts instead of writing them manually. Vertabelo features a reverse engineering function. It allows you to import an existing database structure and build a model of it. If you develop web applications, Vertabelo delivers built-in support for some popular ORMs like Propel (for PHP developers), SQLAlchemy (for Python developers), and JOOQ (for Java developers). The application works completely online and no installation is needed. Just register an account, log in and you can start working on your model from any place in the world connected to the internet.
