What is the difference between scope website and websites?

Question

I know Magento 2 have store, group, website, stores, groups and websites scopes type.

But my question when Magento use singular form and when it uses plural form.

Under core_config_data table sometimes it saves under website or sometime websites scope. How it decide this ?

Answer 1

But my question when Magento use singular form and when it uses plural form.

It's actually the otherway around: only the 'connector_configuration' which comes from the dotmailer module that uses website. So it's inconsistency. You are supposed to use websites or even better, when you're in working in PHP-Code use the constant \Magento\Store\Model\ScopeInterface::SCOPE_WEBSITES

Magento will always use the plural when querying the database!

Prove:

SELECT DISTINCT scope FROM core_config_data will return:

• default
• stores
• website
• websites

SELECT path FROM core_config_data WHERE scope = 'website' will return:

• connector_configuration/catalog_sync/catalog_type
• connector_configuration/catalog_sync/catalog_visibility
• connector_configuration/transactional_data/order_statuses
