|5.||Backup Files||Database is the main container, it contains the data and log files,and all the schemas within it. You always back up a database,it is a discrete unit on its own.||Schemas are like folders within a database, and are mainly used to group logical objects together, which leads to ease of setting permissions by schema.|
