It is the world&#8217;s first fully automated database defined on the principle&nbsp;of *3S*:<\/p>\n<ul>\n<li><strong>Self-driving<\/strong>: Automates database and infrastructure management like provisioning, scaling, patching, backup, and so on. It also includes performance tuning and monitoring&nbsp;tasks.&nbsp;<\/li>\n<li><strong>Self-securing<\/strong>: Protects itself from all internal and external threats and has automatic encryption of all the data in rest or transit.
