Use Singular For Related Key Like Column Id
Related Keys are used inside the portal_catalog. You can define some in the
settings tab.
Related Keys should be named like SQL column ids, because they are virtual columns.
We should not use abreviations.
Good Example:
destination_title
destination_portal_type
grand_parent_simulation_state
Bad Example:
destinationType
Sometimes, we want to specify from which table we will take values (when it
is not the default catalog one).
Good Example:
stock_section_category_uid
Bad Example:
stock_sectionCategory
