SQLite is a database that's well suited for smaller volume applications as it embeds within the application rather than running as a separate server. Cleverly written, it overcomes the issues which have previously pushed even quite limited applications into using a client / server model. And it's built in to many of the products that we teach, so it's likely there and ready for your use.

Now wxPython isn't yet available in Python 3, but PyQt is - although some of the documentation refers ...	2010-05-06
2746	Model - View - Controller demo, Sqlite - Python 3 - Qt4 The Model - View - Controller approach to application design keeps the Graphic User Interface (the view) separate from the database (the model), with the controller in between the two, describing how the data is displayed, and how changes to the data are saved away in the database. By separating the ...	2010-04-29
2745	Connecting Python to sqlite and MySQL databases For developing a Python application, and for light use, the SQLite database may be a good choice ... but then you may want to be able to expand the system to use a central database with a more classic server such as MySQL at a later date.
