PHPMyAdmin is a database tool that has been around since 1998. You can use it to see your database structure and data and make changes. Be careful though, it's easy to break a Drupal site by messing with it's database.
Installing it is really easy, you just need to add this to your .lando.yml file:
services:
phpmyadmin:
type: phpmyadmin
hosts:
- database
proxy:
phpmyadmin:
- phpmyadmin.drupal7.lndo.site
Here, "database" refers to the container name of the default drupal database in lando.
proxy lets us define a URL for the service.
