Describes a relation between two Entities.
The source Entity is the one which owns this Relation object and whose record always holds a reference to the
target Entity. The relation also describes its RelationCardinality.
If the cardinality is RelationCardinality.MANY_TO_ONE, then it means that the source Entity owns the mapping relation Property (which has always type set to PropertyType.REFERENCE). If the cardinality is RelationCardinality.ONE_TO_MANY, the target Entity owns the mapping relation Property.
