Your framework, not ours
Layers, object types and rules are your data. Start from the ready Core model, or shape your own.
Impact that shows its working
What is affected if something fails, and what it relies on. Every result shows the path that explains it.
Your own private copy
Hosted in the EU, at your own address, with its own database. Nothing to install.
How it works
From your spreadsheets to your first answer.
Before you change, retire or move something, you need to know what depends on it, and why.

Shape your metamodel
Or start from the ready Core model: 5 layers, 25 object types.

Bring in your data
Import from Excel with a test run first, or build top-down in the Explorer.

Ask the questions
What is affected if this fails, what it relies on, and a view of any slice to share.
