Commands examples

If the namespace is not used then the commands will perform on top of the default database. bundle exec rake db:create bundle exec rake db:migrate

By using the namespace we are going to use all the configuration for our alternate DB. bundle exec rake store:db:create bundle exec rake store:db:migrate
