Validation of the DMN DRG Dependency Diagram - Gnorion/BizVR GitHub Wiki

NEW VV FEATURE: CHECK THE DMN DRG DEPENDENCIES

In DMN the user must draw dependency arrows manually to show dependencies between tables

Because of this, there is no guarantee that the underlying tables actually do contain a dependency.

This cannot happen in BVR because the dependencies are determined automatically.

So in DMN this can result in a misleading diagram that apparently shows dependencies that really do not exist.

And because the execution of a DMN model requires the dependencies its likely it won't execute.

Validator can now check for this situation and alert the user.

Its still up to the user to confirm that there are real dependencies before drawing an arrow.

more to follow... including examples

In this diagram you can see (side by side) the original DMN DRG with arrow drawn by the user abd the true dependencies as determined by examining the variables set and tested by the underlying decision tables
