Data Modeling: Why Not 3D?

Data Models are meant to communicate structure of information to recipients, who need to understand it. But who are these recipients? In fact, they are human beings. Given that, we should choose our means of communication to be the most effective that we can find. Other professionals have realized this. So what have they done?

They listened to the cognitive scientists and psychologists, and learned that vision is our primary sense (80 % of our cognition is driven from it). Here are a couple of inspiring examples of findings about human perception. First an example of visual reading:

“Rinadeg Oedrr

And then visual recognition:

Just a few visual clues make the difference: You’d better run, now!

Visual cognition is so powerful that we simply must exploit it.

I have an ultimate vision. Let me share it with you using the contemporary paradigm of an Agile user story:

As a Data Modeler I want to be able to use the same kind of 3D tools that other architects use so that I can easily explore and verify my design together with my stakeholders.

This means that all processes should be supported by 3D visualization tools, and that model prototypes should be available in 3D print. Architects (of buildings), designers (of things) and modelers of molecules, among others, do this everyday, now.

They know by experience that visualization of complex structures is what works for discussing, brainstorming, refining and even convincing and selling elaborate solutions. So that is what they do.

The power of visualization is backed up by solid cognitive psychology, and in our own data-centered neighborhood, advanced Analytics is more than saturated with expressive visuals.

Are data models visually expressive?

We are, at best, equipped with 2D computer aided modeling software, and we produce nice engineering diagrams such as this:


ERD diagrams are not truly business-friendly (to be diplomatic). Just like the building architects’ CAD drawn floor plans:


The molecular biologists went 3D a long time ago with their balls and sticks models:

They are printing them in 3D now:

And the architects (and designers in general) managed to go 3D in a responsive manner:


(From augmented reality specialist Augment:

3D printed building models, here is an example:

Can we do a similar thing? And create the same kind of fascination from our “readers”?

I say: Yes, we can! Why not?

Structure can be represented as directed graphs; look at concept models, concept maps or even mind maps. Graphs are visual. There is a short way from the molecule model to a 3D Data Model represented as a graph.

And here is what you can do today for browsing a graph and speak directly to the human cognitive capabilities – remember to come back here after watching 🙂

And why not go all the way? A 3D printed Data Model? Sure thing.

Take up the challenge Data Modeling tool providers! The graph visualization below is PhD work done by Peter J. Radics in a project called OSNAP – The Open Semantic Network Analysis Platform:


Well, Data Models are Semantic Networks too. Don’t miss this train, go 3D now, please.

There is no reason denying it. You, the reader, is also a visionary! We all are. Visualize to get mesmerizing Data Models and data. Graph representations is the Excel of information structures and are immediately fascinating to the human mind.

In up and coming blogs in this space I will inspect more mundane and classic data modeling challenges. But I will always have the vision of a 3D Data Model in my head. Until some software vendor or other makes my day and launches the solution.

If anybody has seen a visual 3D Data Modeling Tool, please let me know!
