It does not bring a specific rule to your main business, ie in most cases we could hire as a service. It is typically a ready-made solution, but can also be outsourced or even developed internally. It is the Domain that complements the main Domain, without it, its main Domain can not be successful, therefore, it is very important, will require internal development or outsourcing, because there is no solution ready to implement. However, Domain-Driven Design is much more than just object orientation. This is where we must put our best efforts, it is what makes the company work, which brings value to the business, which differentiates the company from competitors, is where the greatest focus is placed. Domain-Driven Design is often referred to as object orientation done right. There are three types of Subdomains: Core or Basic Regardless of the size of the company, every Domain can always be divided into Subdomains, by doing this we divide the entire complexity of the Company’s Domain into smaller parts, and we will have domain experts who will understand the aspects of the business very well because it is a specific Subdomain. In simple terms, a Subdomain is a subpart of the Domain. In this way, we are able to separate what in fact generates value and financial return for the company, and thus, strategically we can put our best efforts in that part of the Domain. SubdomainsĭDD requires the decomposition of the Domain into Subdomains, which facilitates our understanding. It is a mistake to think that we can create a single Domain Model for the entire company, if you try to do that it will surely fail. It is from the Domain that we design our Domain Models, which are solutions that seek to meet the needs of the Domain. – Domain that serves as support for the business. – Domain that refers to an area, sector or process of the company. – Domain which is the totality of the Company’s Domain.

One thing we need to know is that the term Domain may have some meanings within the DDD: Domain-Driven Design, or DDD, is an approach for building high-quality software that meets core business objectives. Each company owns a unique Domain, even if it follows ‘market practices’, the company will always have its own way of doing things, its business differential, its brand. We can say that Domain is a scope where one works and how one works, in other words, it refers to the space of the problem for which we are acting, its entities, its behavior and rules. Domain is the most vital concept of DDD, understanding what is Domain is essential for us to accomplish what we call ‘ Domain Distillation‘, which we will address with example in future Posts.
