The Definitive Information to SQLite

Grant Allen and Michael Owen’s e-book on SQLite is a complete take a look at this ‘micro’ database. Regardless of its small footprint, the authors reveal an extremely highly effective engine and a few shocking purposes together with embedded techniques.

Identical to for SQLite, Udemy gives a full nothing-to-something course on utilizing MySQL Databases with Python. The 2 hours of video usefully cowl set up of the server.

MongoDB and Python: Fast begin

Crucially, this MongoDB and Python: Fast Begin two-hour video course covers when to decide on a NoSQL (or doc) database and the important thing variations between this and conventional SQL engines.
