A space is the data container that stores configurations and data. However,
an account can have multiple spaces. It is not possible to share data or configurations
between spaces. If you want to share configurations but have some configurations (i. e.
connectors or payment methods) only applied to one specific case then you should use
space views.
Example
If you have a multishop webshop that uses the same products but you have a country
specific set up with different currency and different translations but the
products sold are identical. In this case you should use one space and separate the different
stores by space views.
