DBENGINE is a management system for using the database system PostgreSQL via browsers like Firefox. You can build multiple databases and configure and use them without logging into the server system. To use the databases, you only need a browser. The system gives you the ability to add own procedure for designing listings and input formulas. You can use binary large objects like any other type of field.

There is virtually no setup required except for specifying your database(s). The available operations, feature set, interface, and user experience is comparable to phpMyAdmin for MySQL.
