ArchiMate Patterns – All Together Now

No man is an island, and no architecture is really complete within a single layer! I’ve written posts for each of the layers independently, and now I thought I’d pull it together and cover how I’ve shown the dependencies between them. First, for those who either haven’t seen them, or just want a handy link to them, the individual layers can be found here:

Realization (Realisation)

The first linkage between these layers are the “realization” relationships between an Artifact hosted within the technology layer (which represents the package, scripts, executables installed on a node) and the logical “Application Component”.

Here, this is a web application being realised by the underlying JAR or WAR packages, and a local application realised by the executable files on a desktop PC.

This is the same pattern used to show the software artifact realising the “System Software” element.

We can also see how a “<<Database>>” Artifact realises the logical “Application Data”, which in turn could realise a “Business Object”.


The serving relationship shows the dependencies between elements which are serve or are used by other elements (although the “used by” description is now deprecated, I still find it a useful term). This diagram shows the Application Component functionality which “serves” (is “used by”) the business layer, and a similar pattern where “System Software” provides services which serve the logical applications, e.g. database or email services.


Finally, there is the “Flow” relationship, and I will do a more detailed post in the future, which shows how data flows from system to system, or in this case between layers. I have found flow to be very useful in highlighting data flows around architectures, especially in a post GDPR world.

All together now

Putting all of these patterns together can allow an architect to build a model and views which can be used to walk all stakeholders through an architecture, highlighting complexity and concerns in a consistent manner.

Hopefully this is/has been useful. I hope to find the time to put a few more posts together with some examples covering the motivation, strategy and implementation layers, as well as specific models which I have used for data protections flows, etc.

As always, these examples are available on Github.
