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.

GNU Data Access

GNU Data Access (GDA) is a set of plugin

, defined as generic as possible, so that any kind of data source can be accessed through them, to provide uniform access to different kinds of data sources (databases, information servers, mail spools, etc.). Similar to Open Database Connectivity (ODBC) or Java Database Connectivity (JDBC), GNU Data Access is a wrapper but with more features to access several database engines. GNU Data Access has been developed as a complete architecture that provides everything required to access data sources. Libgda is mainly a database and a data abstraction layer. It is a

It additionally provides a bunch of tools to help with the development and the management of data sources via the GDA APIs. Libgda was part of the GNOME-DB project but has been separated from it to allow non-GNOME applications to be developed based on it. The libgda library is released under the terms of the
