We all know about relational databases, so I put this talk here because it covers the other kinds of databases.
Databases can be very useful and a real powerhouse for data science projects. Databases have been around for decades and were highly optimised for data aggregations during that time. This presentation will provide a crash course about the major differences of the various database systems as relational, NoSQL and graph databases.
I am looking for editors/curators to help with branches of the tree. Please send me an email if you are interested.
