Database Designer for PostgreSQL is an easy CASE tool with an intuitive graphical interface allowing you to build a clear and effective database structure visually. See the complete picture (diagram) representing all the tables, references between them, views, stored procedures and other objects. Then you can easily generate a physical database on a server, modify it according to any changes you made to the diagram using fast ALTER statements.

Database Representation:
Place objects of your database on a diagram, a virtual sheet of paper. See and realize the structure of your database and its objects: tables, views, stored procedures, functions and relationships between them. Construct schemas, domains, tables, indexes, columns and triggers.

You can import already existing databases to a diagram by reverse engineering.

Easy Database Generation and Maintenance:
With the database designer, you can quickly create a ready-to-use PostgreSQL database with just a few clicks, and then keep its structure up-to-date by synchronizing it with the changes you made to a visual diagram. Simply change the diagram, and the Designer will generate the complex SQL statement for database modification to bring it to the state of the diagram, keeping the data safe. Moreover, you can synchronize several databases to the state of your diagram.

Documentation: Printing, Generating Graphics and Reports:
Generate powerful reports that describe all the database objects within your diagram. You can export a graphical representation of the diagram to EMF, JPEG, PNG, GIF and other popular formats or print the diagram out on multiple pages.
