Relationships

Description

Objects in the model have defined relationships with each other that establish an explicit knowledge graph of the system being modeled. These relationships are either unidirectional (in and out) or bidirectional (inout) and can be traversed by the user while exploring the model. A summary of the existing relationships in Davinci are dicussed below:

Relationships must be given a Relationship Type when created. Select the Relationship Type, then the Relationship Object when creating a new Relationship

Base Relationships

Property	Description
`Uses`	Indicates that one element makes use of another within the model. Can be `in` and `out`.
`Reference`	Denotes that a reference points to another element in the model. Is `out` from the reference object and `in` to its target.
`Performs`	Represents that a part or entity is responsible for performing a specific action. Is `out` from the part and `in` to the action.
`Connect`	Defines a connection between interfaces or ports. Is `inout`.
`Realized`	Indicates that the object realizes some intent, design, or function of another object. Can be `in` and `out`.
`Subject`	Defines the subject of a requirement, linking it to relevant parts, actions, or entities. Is `out` from the requirement and `in` to the target object.
`Mitigation`	Indicates that one element mitigates a risk, issue, or other problem related to another element. Can be `in` and `out`.
`Source`	Indicates the source or origin of the object or its intent. Can be `in` and `out`.
`Impact`	Represents the impact that one element has on another. Can be `in` and `out`.
`Dependency`	Indicates that one element depends on another. Can be `in` and `out`.
`Resource`	Indicates that one element uses a resource. Can be `in` and `out`.
`Validation`	Indicates that the element is validated by another element. Is `out` from the constraint and `in` to the target.
`Transition`	Indicates a transition between states. Is `out` from one state and `in` to another state.
`Result`	Indicates a result of one object occurring as a consequence of another object. Can be `in` and `out`.

Standard Custom Relationships

New projects always start with set of base custom relationships. You can choose to remove these from the project settings view.

All of the following are defined as inout.

Property	Description
`Data`	Represents the exchange of data between parts.
`Power`	Indicates a power connection between parts.
`Mechanical`	Denotes a mechanical connection between parts.
`Optical`	Represents an optical link between parts.
`Chemical`	Describes a chemical interaction between parts.
`Electromagnetic`	Represents an electromagnetic relationship between parts.
`Thermal`	Indicates a thermal exchange between parts.
`Fluid`	Indicates a fluid connection between parts.
