You would use phpMyAdmin in XAMPP to do all your database manipulations.
Select or create your database then look for
Export = dump a database to an sql file
Import = import an exported/dumped database sql file.
There is a Documentation and a Wiki link on the phpMyAdmin main/home page
BTW Dump is a Grey Beard term and has been superseded by the term Export.
Take a look at the new DeskTopXampp
