Introducing data modeling
Before delving into the various data modeling techniques applicable in a distributed environment, it is crucial to first understand what a data model truly is—how it is constructed and formally represented to enable seamless sharing and interoperability.
What is a data model?
In Chapter 4, Identifying Data Products and Prioritizing Developments, we discussed how, in domain-driven design (DDD), modeling the domain where the problem resides—what we call the problem space—is fundamental to crafting an effective solution. But let’s unpack what a model really is. At its core, a model is an abstraction, a tool that enables us to navigate the intricacies of a domain by stripping away the noise and focusing on the elements that are truly critical to solving the problem at hand.
A model is a simplified representation of a thing or phenomenon that intentionally emphasizes certain aspects while ignoring others. Abstraction with a...
