From Chaos to Clarity: How DDD Aggregates Can Transform Your Models



Published
Even with the simplest domain model we can get into problems fairly fast and everything becomes chaotic. Fortunately, DDD aggregates are a good way to bring some clarity into your domain model. DDD aggregates represent a cluster of domain objects that we want to treat as a single unit. This ensures DDD aggregates become a boundary of consistency in our domain. In this vide I explain what DDD aggregates are, when they are useful and how to design them.
