GNOME-DB
GNOME-DB is a database application by the GNOME community. The project aims to provide a free unified data access architecture to the GNOME project for all Unix platforms. GNOME-DB is useful for any application that accesses persistent data (not only databases, but data), since it now contains a data management API.
Support for GObject Introspection and Vala.
Starting with the 4.2 series, GNOME-DB corresponds to the libgda library.
The libgnomedb library provides "widgets" that allow users to interact with data in databases. It uses the libgda generic database API, so it can use MySQL, Postgres, Sqlite, etc.
