Exploring DDD and its significance

DDD is a software design approach that encourages us as developers to assess processes and subprocesses and decipher all the atomic elements therein. Atomic means that one process might have many moving parts, and while they all combine to give one output, they have their own routines to carry out. Each subprocess can be seen as self-governing and can further be attributed to a domain. This motivates us to break up a monolith into independent microservices that do their own thing against their own data. That is a domain.

Before we go much further, let’s take some time to explore certain keywords and their definitions:

• Models: These are abstractions that define aspects of a domain and are used to solve domain problems. We organize information about the target domain into smaller pieces and call them models. A model is a central point of reference in our design and development process. These models can then be grouped into logical...
