Display virtual (multi-hop) relationships with the Advanced Relationship matrix

End-to-End Traceability

The Model Expert Advanced Relationship Matrix provides an end-to-end view of traceability in your model. Which means you can confirm the dependencies that exist between elements that are only distantly connected, without having to display every intermediate step.

When elements are not connected directly, but are related through several relationships and elements, they may never appear on a diagram together. But there is a connection. It may be deliberate, or accidental. But you still need to know about it.

Model Expert makes it easy to view these ‘virtual connections’, so you can discover more about the systems and processes you have modelled:

  • identify accidental dependencies
  • spot where there is missing data
  • provide a summary view to your senior stakeholders without the ‘working out’

In this example model, Actors are connected to Tasks, through 3 intermediate elements and four intermediate connectors.

The quickest way to find out which Actors are connected to which Tasks is to create a Model Expert Advanced Relationship Matrix.

Choose the route through your model

To create an advanced relationship matrix, you need to specify the element and relationship types for Model Expert to follow.

Do this by:

  • First choosing the reference model with your approved metamodel
  • Select the package containing your source elements
  • Choose your source element type
  • Then just follow the path through the tree view to the target element type you need.
  • Easy!

(Note you have to choose just one path from source to target – so if your reference model allows several ways in which your source and target are connected then you will need to create an advanced matrix for each of those paths.)

Why do I need a Reference Model?

Without a Reference Model, the relationship matrix doesn’t know the pattern of connectors and elements that you expect to see. If it analyzed the whole of your raw model then there would be too many options to display.

So start by creating a snapshot meta model to see all the element and connector types that exist – use it to create and edit a reference model and then define the virtual relationships you need to view

Virtual Connectors made visible

The relationship matrix created shows which source and target elements are connected, no matter how many relationship steps are between them. The matrix definition is saved in your model, so you can access it from the project browser to regenerate as your model is updated.

As the relationship between each of your source and target elements in the matrix is virtual, the cells of the matrix just show that a relationship exists. To discover the intermediate detail, for each of these virtual relationships, simply create a diagram from the matrix.

Advanced Relationship Matrices can also be exported to Excel or added into your documents.
