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
