Declarative Modelling Languages: Unveiling the Power of Understanding Severity Levels

I want to thank Maria Keet for showing us the different levels of declarative modelling languages. It began with a Mind Map and ended with an Ontology. I am astounded by the number of options available to help us make sense of a domain. It struck me how few options I use when starting a new domain adventure.


Biology Model (Maria Keet)

All too often, I go straight to Entity Relationship modelling, and there have been cases where I have had to stop using either ERM or Dimensional modelling because it is not getting the results it should.


Start simple and progress when you need more clarity (Maria Keet)

Sometimes, studying Data Modelling languages feels like trying to understand Autism Spectrum Disorder (ASD).

There are benefits for all the severity levels of the spectrum. Understanding and working with the severity levels allows you to get spectacular results. However, a lack of understanding can also lead to some terrible failures. The potential failure underscores the importance of awareness of the severity of getting the models wrong.

Do you have too many choices and options or too few?

Too many options are not beneficial, and Data Governance and Architecture can quickly fall into the trap of regimenting the choices. This regimental approach can lead to the challenge of forcing a square peg into a round hole.

How do we find the balance and make the best decisions depending on the severity level? This is where your decision-making skills come into play, ensuring the best outcomes in data modelling.


Lots of moving parts that need to fit together (Maria Keet)

Playbooks are essential for the organisation to know how to conduct a play. More importantly, the right coach to choose the correct play for the business problem.

In summary, this is why understanding the different declarative languages is so important:

  1. Having options that you can play.
  2. Knowing the conditions for success and failure
  3. Having the right people to choose, lead and perform the play. Don't underestimate the team's impact.

In the words of an astute coach, pay attention to the tension. It means your choice may not be fitting.

This is good ! Modeling must always start within the business domain, without any bias from a technical perspective. The path for doing this must always be something that is adapted to the situation. Mind mapping is a very good tool for a lot of things when trying to grasp the real concepts usable for the business. But still, the quality depends on the experience and flexibility of the modelling team. Nice presentation and well done 🙏🏻
