A critical aspect when implementing DDD is the correct definition of the Bounded Context (Contextos Acotados in Spanish). This will allow us, in turn, to define the aggregates and other elements of our system. Ubiquitous Language plays a decisive role in defining each of our bounded contexts.
One of the first things you hear when talking about DDD is the term "Ubiquitous Language". It is the basis of everything in DDD, using this language we will be able to define all the concepts of our business, it will help us communicate correctly and above all, it will facilitate the task of correctly modeling the domain of our solution.
Value Objects (VO) are a fundamental piece of Domain-Driven-Design (DDD) and object-oriented programming. They describe a concept of our domain layer.
