+# Databases
+
+-------------------------------------------------------------------------
+
+Skynet 2.0 had databases to manage.
+
+-------------------------------------------------------------------------
+
+Now most applications we built use sqlite
+
+-------------------------------------------------------------------------
+
+Some programs on nixos use mysql/postgresql
+
+-------------------------------------------------------------------------
+
+# Sqlite
+
+-------------------------------------------------------------------------
+
+Sqlite is a single file database.
+
+-------------------------------------------------------------------------
+
+Uses a subset of SQL
+
+-------------------------------------------------------------------------
+
+Very easy to backup (single file)
+
+-------------------------------------------------------------------------
+
+# Postgresql
+
+-------------------------------------------------------------------------
+
+Full fledged Database server with roles and permissions.
+
+-------------------------------------------------------------------------
+
+Full SQL (and sometimes more)
+
+-------------------------------------------------------------------------
+
+Our servers are managed by Nixos.
+
+-------------------------------------------------------------------------
+
+Not so easy to backup, export command needs to be used.
+
+-------------------------------------------------------------------------
