Installing Oracle VirtualBox and configuring a virtual machine

This video is the first of a complete videotutorial course about PostgreSQL – usage and management – that is under construction but it will be released in a couple of weeks. The course is focused on teach you how to install PostgreSQL on Windows or Linux, configuring it and tuning it, learn the basics of DML and DDL, learn programming language PL/pgSQL, triggers, backup and restore, using command line tools like psql and so on. This first video isn’t about PostgreSQL, it’s about installing and configuring VirtualBox. The idea is to install PostgreSQL on a virtual machine to simulate a remote database server, or to teach you how to install it on Linux if your computer OS is Linux.
