Gets the array of many-to-many relationships for the entity. Gets the array of many-to-one relationships for the entity. Gets the array of one-to-many relationships for the entity.

If either of these properties return false, this is indicated.

The purpose of this separation is to focus on the columns a developer can set when creating or updating rows in a table.

Only those properties expected to be most useful for developers are included. This section includes selected entity properties rather than all of them.
