Description

In this hands-on lab, we will focus on modelling business rules and constraints.

Business rules and constraints are everywhere. They can be the backbone of a business process or accidental to guide the business flow in the right direction. By writing them down explicitly as first class concepts, we get a number of benefits:

  • We can discuss them with the domain experts;
  • We can connect rules with the events that affect them. This helps to uncover hidden dependencies;
  • We can use them as a guide to design boundaries. They can even help us to spot where our bounded contexts aren’t as isolated as we’d want.

Let’s upgrade our EventStorming by modelling business rules and constraints more granularly than ever.
