The video on this page will show you most of the functions of the database project. It does not have audio and will go rather quick through a lot of stuff. It is kinda long but it should give you a rather good impression of how it works and what you actually can do.
Please note – this video shows version 2.0 of the project. There was a newer version released that has even more modules and improvements. Please see the release notes for details. The video will still give you a good idea of the actual project.
