Manage your WordPress database with Adminer plugin
Adminer is a management tool that resembles phpMyAdmin, but works directly from a blog’s dashboard.
You can use Adminer for basic database operations to avoid opening the control panel of your hosting provider to use phpMyAdmin.
Adminer is able to restore a database backup, zipped or not, is easy to use and is reliable.
Do you really need it? Perhaps not, unless DB work is something you do frequently.
