Since I retired from the development of GNOME-DB (mostly because I haven’t used a database for years) and left Vivien the liberty to do what he wanted, the project has been improving over time, and with the latest 2.0 beta release the libraries are in a very good shape. Lots of missing features have been added, API has been greatly improved, which makes it suitable for all kinds of application developers. So expect some more DB-love (GNOME Office, Glom, etc) in your GNOME desktops in the upcoming release cycles.
