About relations and relation types

A relation is a characteristic that describes how two assets relate to each other. The relation's type defines the relation and determines which assets can be related.

You can add a relation between assets if the relation's type is in the relevant assignment of the asset's type.

Elements in a relation type

A relation type has four elements:

Element	Description
Head	Asset type of assets that can be the head of the relation.
Tail	Asset type of assets that can be the tail of the relation.
Role	The description of the relation type going from the head asset to the tail asset.
Co-role	The description of the relation type going from the tail asset to the head asset.

Note Relations are bidirectional. For example, in the relation type "Table is part of/contains Database", the Table asset is part of the Database asset, and the Database asset contains the Table asset.
